[2023] DLC are not visible when bought via Steam

Hi,
I recently bought Anno 1800 on Steam platform. After that I bought 5 DLCs (on steam platform), however two of them are not activated once i lunch a game.

DLCs which are not activated:
- Bright Harvest
- Seat of Power

Rest of DLCs are fine and are visible in the game.

What I did to fix the issue:
- Reinstall Anno 1800
- Reinstall Ubisoft Store
- Verify local files on steam
- Clean cache on steam
- I tried to create new account on Ubisoft Store and link that account to my steam account - suprise, when activating game DLC was listed to being activated, but then Ubisoft reject me, because game was assigned to different account.

What's going on?

PS. I created a ticket - but for two weeks it is withour any response.
