Missing expansion packs

Also I own 15 add ons/expansions and they are visible in the manage add on sections. But while playing the actual game it requires me to purchase. I even went as far to select one to see what it would say and the manage option appeared, so Microsoft is even acknowledging that I have purchased them. But somehow they have disappeared overnight. I’m not understanding this and I’ve spent a lot of money into this game for things to just vanish. I’ve also did every troubleshooting step that was given and still nothing. Please help.
