Mysterious black block on the rightmost screen in my 4 Monitor setup and transparent MFD

[Vango]

I configured it with Helios but its doing this weird <profanity>. I have a black block on the right side of the screen. The first Monitor is not at the picture, it have only the left and right MFD on it.

So in my opinion i did nothing wrong, why is it doing that? I tried the 3 Monitor setup from dcs with the config for Left, Center and Right but that looks weird af. Any ideas??

And the second problem i encountered is that the center MFD is transparent. Dont know why but i would like to change it.
