Base game classes aren't showing up in CAS?

Forgive me if I posted this the wrong place :| But as the title says, my base game glasses aren't showing up in CAS. I figured out that it has something to do with my custom content, since they are back, when I take the mods folder out. Sometimes they appear when I randomize a sims long enough, but it happens rarely, and it's making me really mad

It started after the new patch, at first I thought that I just needed to update all my CC, but even after I did it, it's still the same.
I really don't want to let go of my custom content, so I wanted to know, if anyone knew what the problem could be? Right now, I think i'm the only one that has this problem, but I wanted to know if anyone has the same/similar problem and knows how to fix it

I really hope it was understandable enough, and please tell me if you need to know more :)
