Sims 4 Packs not loading into game while installed.

I re-downloaded the Sims today after having to delete it due to storage issues, and my packs seem to be playing up. 

When I open the game, all of my Steam packs are loaded and working fine, but all of my EA App packs say they aren't installed when they are. I have tried to uninstall the game on both steam and EA App, running it through steam and then EA App first, but nothing seems to be working.
