Some of my bought dlc no longer appear in game

I do usually play with mods, BUT I removed everything - including cc. I have majority of my dlc but 7 of them aren't appearing in my game : Discover University, Cottage living, high school years, backyard stuff, blooming room kits, modern luxe kit and desert luxe kit. I've repaired my game through steam - didn't work. I'm at a lost. I don't have receipts because I bought these at different times, and I don't feel like going on a wild goose chase.
