Hi SilverStripe Forum,

I installed the slideshow module: http://www.silverstripe.org/slideshow-module/

Everythings works fine but the "update slideshow" setting. I can choose:
- Apply to this page only
- Apply to all slideshows in this section
- Apply to all slideshows on this site

However.. Apply to this page only is the default option. Whenever I try to change it it stays on "Apply to this page only".

Is there anything I need to take attention to?

I added this line for each PageType to the _config.php.

DataObject::add_extension('PageType', 'Slideshow');
