I've been utilizing the sitetree option for 'Show only changed pages' for a while now. I recently added a new page type and the functionality for the sitetree broke down. All the pages within that option in the sitetree are now black and when clicked the CMS is refreshed and I'm kicked out of that mode. Attached is an image to reference how it looks.

I attempted to do some trouble shooting to understand where the problem started. If I remove that custom page type, then the option works fine. So I put it back in and stripped the page to its bare minimum, and the option for 'Show only changed pages' broke again. So I cleared it out and made a new page type, again the 'Show only changed pages' option stopped working. It's weird because it was working with custom page types up until the other day.

Has anyone else experienced this problem? Does anyone have any ideas for me to try. Thanks in advance for the help!
