Screen Resolution AoM T&D not working in FHD

Dear Community,
since last AoM T&D update my screen resoltuion doest work in FHD. Game starts in FHD, but if the single player game for example is started the game is not in FHD. I resintalled the game, checked driver and windows updates, forums but nothing fixed the issue. Does anyone has same problem or can help me?
CPU: AMD Ryzen 5 1600
GPU: Nvidia Geforce GTX1060
DirectX: 12
OS: Win 10 Prof. 64Bit
newest patches driver updates, etc

I installed windows 10 complete new and checked update, driver etc, but same failure. So I think its a bug in the game.

As far as i can say from the screenshot there is no issue. Tho i always suggest turning off V-Sync.
