I have the same thing. Currently installed the deluxe edition on my Xbox One and installed the game and all the add-ons, and none of them are showing. When I go into the Microsoft store it says installed but I can buy to own. I've deleted and reinstalled all, reset my account and started a new game save and as it said all weren't installed and then still doesn't show. I changed my home Xbox and still nothing.
How do I fix this?
