How to uninstall a pack?

Can't uninstall packs. However, you can DISABLE packs by using this page right here. There you go, just follow the instructions on the website and your problem is solved.

oh thanks but I didn't want it disabled - I wanted to uninstall and reinstall to see if a bug would fix. When I move sims into Copperdale they appear in Sulani too and also they appear homeless

eta - I already repaired the game and removed all mods - no change
