Dual Screen issue

I work with 2 screens but in a vertical setup where one is on top of the other due to limited space. The program works well but when opening the program or a new song, the saved work-space never opens on both screens, only the bottom project window opens leaving me having to drag the top mixer window manually every single time.
I have played with all the monitor setups on the graphics card and windows itself and saved them over and over again, but it will not save my setup.

Not sure what is at fault here but if anyone has any ideas and had a similar problem, I would be grateful for a heads up.

Thanks in advance

Yes same issue since 8.5
