[SOLVED] CC doesn't show up in S4S catalogue?

Hi! So you know that screen that pops up when you click the big CAS button above the radio buttons? It normally shows off every swatch option for every article of clothing in Create a Sim. Apparently, it's also supposed to show you custom content????? Which, I mean, makes sense, there's a CC option in that content drop-down menu. It's just, every time I've ever tried to sort by custom content, I see nothing. I *definitely* have CC installed. It's buried in a few sub-folders, so I tried moving some to the root Mods folder, still nothing.

What am I doing wrong? Do I need to change a setting? Move my CC? I'm so confused. I kind of thought this was universal until I saw a YouTube video a few minutes ago.
