CCR Mode: Changing of the Stepoint depth leads to a reset

When I want to change the depth in the automatic setpoint option, the Descent makes a reset and starts again.

It happens with both setpoints, the lower and the upper one.

So I cannot change the setpoint depth and have to dive with the manual option.

This seems to be new with SW 10.20 or 10.10. I got a new Descend some weeks ago. The older one worked fine.

Is it a sw-bug?
