HW2 DLC won’t work

I purchased the Icons of War DLC from the Microsoft store, however it won’t let me use it in game. I am not the only person to have been scammed because this bug is constantly overlooked. I would like a solution to fix this bug not only for myself but also for the people who have the same issue.

Ive tried uninstalling the DLCs and re installing them, that didn’t work so I uninstalled the entire game with the DLCs and installed it all again, still didn’t work, I tried individually installing them still won’t unlock in game but in the store it says I already own the product. I look in the “Manage game & add-ons” and it says that the DLCs are installed. The Leader Forge works just fine, just not the Icons of War DLC.
