QGroundcontrol PX4 Motor test command not supported

I build S500 V2 model with PX4.
Firmware version 1.10.1

I made all calibrations, all are green.
Connected the 3S 3100mAh battery, fully charged.

Then I try to test motors:
I enabled “propellers are removed” switch,
when I try to move slider for any motor I get the error “Motor test command not supported”.

What is wrong?
What can I do ?
