Six of my Sims 3 Packs are not showing up in the launcher

Hello! I have been having trouble getting all of my expansion and stuff packs to show up in my Sims 3 launcher.

I have every Sims 3 expansion and stuff pack, and they all appear to be downloaded when I open the EA app and check. However, when I look at the expansions and stuff packs that are selected in the launcher, six of my expansion packs are completely gone.

These packs are Generations, University Life, Pets, Seasons, Supernatural, and Island Paradise.

If there is any solution to this issue, please let me know. I have been struggling with this issue for around three years now, and I just want to be able to play my game in its entirety. I feel like I have tried everything and I am stuck at a wall trying to figure out what to do next.

Any help is much appreciated!
