Gallery “Include Custom Content” Not Working

I’m having an issue where I go into CAS, open My Library or Gallery, and turn on “Include Custom Content”, but nothing shows up. It’s like everything with CC doesn't exist. I already checked and made sure CC & Mods are enabled in Game Options, so I’m not sure what’s causing it.

I've tried Clearing Cache, specifically localthumbcache package, avatarcache package, and everything inside of cachestr. I've tried Removing My “Tray” Folder, with no change in the Gallery either. I've tried Repairing the Game, and I've tried testing it with a brand NEW The Sims 4 folder, and it still isn't working!!

I am at a complete loss for what could possibly be wrong. Has anyone else had this happen or know how to fix it?? Any help would be really appreciated!
