Motor keeps spinning constantly while attempting motor setup in QGC

I’m attempting to test my motor using the sliders under vehicle setup in QGroundcontrol. When I move the slider a bit and it spins slowly as it should. However after the slider returns to its original position, the motor suddenly starts spinning at full speed and does not stop unless I manually unplug it from the ESC.

I’m using PX4 version 1.12.3 dev for mini talon.

Has anyone ever encountered this or any similar issue before? And if so could you help out?

Thanks in advance

This sounds like a bug. I would assume that this has been fixed in later versions, e.g. v1.13.2. Have tried that?
