Qgroundcontrol Joystick problem Ardurover

Hi

I use 4 axis joystick with ardurover 4.1.0 dev. In misiion planner all axis are visible and work in joystick window and RC radio calibration window.
In Qground control all joystick axis are visible and work in configuration joystick window but in window radio calibration work only two axis of joystick.

I tried make calibration radio again use joystick but it nothing changed.

Why groundcontrol use only 2 axis of joystick to RC control?

Thanks
