Saves and CC not showing up, with only one folder

So, I've been having this issue for awhile now. Some time ago, after I updated both Origin and the Sims, my save files weren't showing up in the game.

I've tried everything I could find- making a new sim and restarting to see if the files would show up, renaming my save files, checking for any extra Sims folders, and even reinstalling the game, but to no avail. I know the issue is that there's another Sims 4 file somewhere, but no matter where I search, I can't find it. I don't use anything to save files such as OneDrive and Google Docs, and I even double-checked those places. It'd be okay if I lose my saves, but if I can't find this file or whatever the issue is, I won't be able to play with custom content and mods.

All of my saves, tray items, and mods are still there, in the one Sims 4 folder in the Electronic Arts folder in my documents. They just aren't showing up in the game. If anyone has any advice or questions that could help, I would greatly appreciate it. I've been trying for days now, and I really hope I will be able to salvage this game, because I personally think the base game is too boring to play without any custom content. Thanks in advance.
