Docking Modules won't open

The Pan&Zoom, Frame & Focus, Filter Wheel and Tec won’t open when I select them at the view menu; all the others work well.
Same result if the camera/filter wheel is connected or disconnected. I can control the camera and filters in the control panel. Everything else is working, I can take pictures, run auto focus, even plate solve. I have downloaded and re-installed SGP a few times.

Equipment:
Windows 10
SGP version 2.6.0.23
QSI 6120 with filter wheel
