Sims 4, mods appearing in game even though there's none in the mods folder

Hi, I've been playing Sims for years now but I've only been using cc and mods for about 3 years. After a recent update, about 3 weeks ago, my game completely reset. All my save files disappeared, all my mods disappeared. So I spent a whole day trying to get back as much of my cc and mods back but when I began moving them into the Mods folder, I got a pop-up saying that all of those files already exist in that folder. But since they weren't appearing in the game then I replaced the old files with the freshly downloaded ones and went into the game. I got over the fact that my save files weren't coming back and I started a brand new game with a fresh sim. But whilst in CAS I realised that only about 30% of the cc and mods I downloaded were actually in the game. Still, I got over it and just began playing, I was playing on the new save file for about 2 weeks and a new update came (yay! :/). Of course I had to download the updated versions of UI Cheats and MCCC. However, the version of MCCC that was in my game prior the update was 8.1.1, the updated version was 8.1.2. I downloaded version 8.1.2 and deleted the previous version completely off my computer. I then proceeded to open the game and was slightly surprised to see that the version of MCCC which was apparently installed was 8.1.1. (When MCCC is installed you get a pop-up after going into a household, which tells you which version you have installed.) I closed the game and quickly wanted to test out my theory. I took all my mods out of the Mods folder, and into a new folder on the desktop, and then opened my game with no mods installed, every single mod which appeared in the game a few minutes earlier was still in the game. It's like the mods are permanently stuck in the game. I feel like I've tried everything, please help. 😢
