Purchased expansion packs will not download because I "do not own" them

I purchased the snowy escape pack when it first came out and this has been an issue ever since. Every time I try to download the pack through the EA app it says I do not own it even though I do. In the add on store, it says that I already own the pack too. I have tried clearing the cache, repairing the game, and everything else I could think of. I also tried contacting EA support and they were unhelpful with this issue. Does anyone have a solution for this?
