Can't import save files

So I backed up my campaign saves before reinstalling windows and then I placed them back in Documents/Warcraft III/BattleNet after the reinstall but the game doesn’t see them. Not only that, but the portraits unlocked from completing the campaign are locked again as well. Did I do something wrong? I really don’t want to play this game on hard again…

EDIT: Funny thing, the portrait I had is still in use, even though it’s locked.
