Hello Lushquotient713,
First, please try the following steps to be sure your packs are all properly installed to your console:
- Highlight The Sims on the dashboard
- Press the Menu button on the controller
- Select "Manage Games and Add-ons"
- You should see an option here to "Install" your DLC
If your packs are showing as unowned here, it sounds like you may be logging into your Xbox with a different Microsoft account than the account you had originally purchased your packs on. You'll want to review the transaction history for your Microsoft account and check for your missing packs there.
