CAS items not showing up in S4Studio... but objects do

Hello, I'm new to this whole CC stuff.

I've just installed the newest version of S4Studio, as well as reinstalling Sims 4, trying to follow a youtube tutorial, but when I click on the "CAS" button nothing is showing up despite having "all" set for all filters.

I've checked multiple times whether all paths are set correctly (they are), and when I tried the "Objects" button instead everything showed up just fine.

I don't have any mods, CC or DLCs/Packs/whatever. Just the base game.

I'm at my wits end with this, thanks for any help and advice in advance.

EDIT: For some reason, the problem just fixed itself after a restart, despite me having restatrted it multiple times before. Thanks anyways!
