Scribe/Upfront Help: Pages/menu items edited from back end not syncing

Hi,

I'm currently using Scribe theme and usually edit back and forth between back end and upfront. I notice that some of the menu items I added on the back end (the blog categories: recipes, recordings and the Log Out) are not visible. Also the BuddyPress pages such as the members page appear blank. Only when I deactivate Scribe and run twenty fifteen do I see the menu items and pages.

Similarly the pages I edit with Upfront: Home, Services, About are missing elements added/edited with Upfront when I run twenty fifteen.

Am I missing something with the Scribe theme and/or Upfront?

Thanks.
