De-rotation not working - spins fast and doesnt stop. iOptron AZMP mount

[Bryneth]

Having issue with a new Falcon V2.

Coonecting to mount iOptron AZMP all ok, and de-rotation correctly calculated by unity.

When turning on the de-rotation the rotator starts rotating very fast and deosnt stop.

I've treid v1.4 and v1.3, reset app and rotator.

All other function operate as expected.

Is this a bug in unity? faulty unit? or is there anything else I can try.
