Switches and Buttons in QGC

I am setting up Qgroundcontrol (QGC) for Radio.
The Joysticks can simply be adjusted and I see them moving. But in the last step the switches I don’t see. The switches must be switched over the entire range (2 and 3 steps). Nothing happens in QGC, the channels remain the same. In my RC FlySky I have set up 10 channels, 6-10 for switches and buttons. Their working is visible in the RC. Does anyone have an idea why I don’t see this in QGC?
