Custom Cast/Custom Crew

I use Movie Collector for Windows version 23.3.5. I just recently had to resync my collection from the Cloud. Now, for my DVD entries, I am seeing in the Cast & Crew tab a “Core Cast” tab next to a “Custom Cast” tab, and a “Core Crew” tab next to a “Custom Crew” tab. How do I get rid of these so that only “Cast” and “Crew” displays?

These toggles control wether the cast you’re using is the one from Core, and thus disables editing on them (so you always get the Core cast updates from us) - or if it is custom cast, meaning you do all the editing/adding of your cast members.

And then the same for Crew of course.
