Game installation

I recently transferred over my Sims 4 game and the expansion packs to my new Xbox one series X Console. In the game section it is showing that the game and all my packs are installed, but when I go into my Sims game, to start playing, none of my packs are accessible. It shows they are unowned. So I uninstalled the game and reinstalled it and it’s still not showing up. I really don’t want to have to buy all of those packs again so I’m hoping you could help me figure something out.
