My (Gallery) Library not showing my stuff

Long story short, i have these sims I every new pack, yet they aren't showing up in the My Library tab in the gallery (I never shared them). i searched online for answers and fixes, but nothing worked. Before this, I've never messed with the tray folder, but everything seems to be there. Even Curse Forge doesn't recognize them like it usually does. I'm at a loss for what to do; please help.
