Steam requires the purchase dlcs second time

Hi,

I used MFS2020 in the Microsoft store for 2 months and uninstalled it. During this time, I bought a lot of expansions for the game.

I purchased MFS on Steam, installed it, logged in to the same account I used earlier and where the add-ons should be. There are no extras and the MFS store requires re-purchase. What to do? Aren’t add-ons in MFS tied to the game and user account, only to the platform? It’s stupid

Do I have to buy add-ons a second time just because I log in to the game via Steam and not via the Microsoft Store as before?

Please help
