5.1 panning windows is just grey

Hello there.

Today, all of a sudden - all my 5.1 panning windows have turned grey, with a white border.
Anyone know what this could be?

Choosing any specific output in routing changes it to the normal C L/R panning controls as it should, but when set to 5.1 it’s just great and cannot be controlled.
I can map quick controls to the panning and control it, but cannot see anything visually.

This first happened when I created a new project and wanted to make a really short sound design thing, now when I open all older projects too, it’s like this.

Any help is greatly appreciated as this sets me back quite a bit when I can’t work.

Thanks in advance.
