Nested HasOneDOM not Writing Relation

I have a bit of complex nested HasOneDom thats not writing the Relation ID's and I've been banging my head against it and not getting anywhere

Here's the Parent Relation

static $has_one = array(
      'BundlePage' => 'BundlePage', //Holding Page Type 1
      'FeaturePage' => 'FeaturePage', //Holdeing Page Type 2
      'IlsItem' => 'IlsItem', //Sibling relation
      'ThisBundleQty'=>'BundleQty' // Child Relation
   );

And Here's the code that generates the popup

   public function getCMSFields_forPopup()
   {
      //This Part just Builds the Form Based on the type of Item the Sibling it Is
      if($this->IlsItemID){
         $ilsItem = DataObject::get_by_id("IlsItem", $this->IlsItemID);
         $upcs = DataObject::get("IlsUPC", "IlsItemID = ".$this->IlsItemID);
         
         if ($ilsItem && $ilsItem->CollectionBook == "Eyelash") {
            $sizeFields = array('GenQty' => 'GenQty');
            $finalSize = "Gen";
         } else {
            if($upcs) {
               if ($upcs->count() == 1) {
                  $sizeFields = array("OneSizeQty" => "OneSizeQty");
                  $finalSize = "OS";
               } else {
                  $sizeArray = array();
                  foreach ($upcs as $size) {
                     array_push($sizeArray, $size->Size);
                  }
                  if(in_array("32B", $sizeArray)) {
                     $sizeFields = array(
                        '32AQty' => '32AQty',
                        '32BQty' => '32BQty',
                        '32CQty' => '32CQty',
                        '34BQty' => '34BQty',
                        '34CQty' => '34CQty',
                        '34DQty' => '34DQty',
                        '34DDQty' => '34DDQty',
                        '36BQty' => '36BQty',
                        '36CQty' => '36CQty',
                        '36DQty' => '36DQty',
                        '36DDQty' => '36DDQty',
                        '38BQty' => '38BQty',
                        '38CQty' => '38CQty',
                        '38DQty' => '38DQty',
                        '38DDQty' => '38DDQty'
                     );
                     $finalSize = "Bra";
                  } elseif(in_array("M/L", $sizeArray)) {
                     $sizeFields = array(
                        'SMQty' => 'SMQty',
                        'MLQty' => 'MLQty'
                     );
                     $finalSize = "SMML";
                  } else {
                     $sizeFields = array(
                        'SmallQty' => 'SmallQty',
                        'MediumQty' => 'MediumQty',
                        'LargeQty' => 'LargeQty'
                     );
                     $finalSize = "SML";
                  }
                  
               }
            } else {
               $sizeFields = array("nonefound" => "nonefound");
               $finalSize = "All";
            }
         }
      }
         
      return new FieldSet(
         new DropdownField('IlsItemID', 'Choose an Item', $this->getBaciItems()),
         new HasOneDataObjectManager(
            $this,
            'ThisBundleQty',
            'BundleQty',
            $sizeFields,
            'getCMSFields_forPopup'
         )
         
      );
   }

Now Here's the Child DataObject

class BundleQty extends DataObject {
   
   static $db = array(
      'SmallQty' => 'Int',
      'MediumQty' => 'Int',
      'LargeQty' => 'Int',
      'OneSizeQty' => 'Int',
      'SMQty' => 'Int',
      'MLQty' => 'Int',
      '32AQty' => 'Int',
      '32BQty' => 'Int',
      '32CQty' => 'Int',
      '34BQty' => 'Int',
      '34CQty' => 'Int',
      '34DQty' => 'Int',
      '34DDQty' => 'Int',
      '36BQty' => 'Int',
      '36CQty' => 'Int',
      '36DQty' => 'Int',
      '36DDQty' => 'Int',
      '38BQty' => 'Int',
      '38CQty' => 'Int',
      '38DQty' => 'Int',
      '38DDQty' => 'Int',
      'GenQty' => 'Int'
   );
   
   static $has_one = array(
      'BundleItem' => 'BundleItem'
   );
   
   
   //I had to use a hacky way to get the figure out which of the fields to render in the form
   public function getCMSFields_forPopup()
   {
      if($this->BundleQtyID){
         $bundleItem = DataObject::get_by_id("BundleItem", $this->BundleQtyID);
         $ilsItem = DataObject::get_by_id("IlsItem", $bundleItem->IlsItemID);
         $upcs = DataObject::get("IlsUPC", "IlsItemID = ".$ilsItem->ID);
         
         
         if ($ilsItem && $ilsItem->CollectionBook == "Eyelash") {
            $listFields= "Gen";
         } else {
            if($upcs) {
               if ($upcs->count() == 1) {
                  $finalSize = "SML";
               } else {
                  $sizeArray = array();
                  foreach ($upcs as $size) {
                     array_push($sizeArray, $size->Size);
                  }
                  if(in_array("32B", $sizeArray)) {
                     $listFields= "Bra";
                  } elseif(in_array("M/L", $sizeArray)) {
                     $listFields= "SMML";
                  } else {
                     $listFields= "SML";
                  }
                  
               }
            } else {
               $listFields= "All";
            }
         }
      } else {
         $listFields= "All";
      }
      if($listFields=="OS") {
         return new FieldSet(
            new TextField('OneSizeQty')
         );   
      } elseif ($listFields=="SML") {
         return new FieldSet(
            new TextField('SmallQty'),
            new TextField('MediumQty'),
            new TextField('LargeQty')
         );
      } elseif ($listFields=="SMML"){
         return new FieldSet(
            new TextField('SMQty'),
            new TextField('MLQty')
         );
      } elseif ($listFields=="Gen"){
         return new FieldSet(
            new TextField('GenQty')
         );
      } elseif($listFields=="Bra") {
         return new FieldSet(
            new TextField('32AQty'),
            new TextField('32BQty'),
            new TextField('32CQty'),
            new TextField('34BQty'),
            new TextField('34CQty'),
            new TextField('34DQty'),
            new TextField('34DDQty'),
            new TextField('36BQty'),
            new TextField('36CQty'),
            new TextField('36DQty'),
            new TextField('36DDQty'),
            new TextField('38BQty'),
            new TextField('38CQty'),
            new TextField('38DQty'),
            new TextField('38DDQty')
         );
      } else {
         return new FieldSet(
            new TextField('OneSizeQty')
         );
      }
      
   }
   
   

}

This writes the dataobject okay,but when I click on the parent object to edit I get a list of All the BundleQty s with a radial select. Selecting one and saving doesn't write the relation either.

Any help would be appreciated. Please excuse the hacky code

Cheers
