Output-Problem: Can't set the Direct Output to "Guitar Analog" when Rig Manager is running

I just discovered the problem that I can't adjust the "Direct Output" knob from the Output-menue to "Git Analog" or "off" when the Rig Manager is running on a KPA-connected PC. The value jumps back immediately to "Git+Processing" every time I try to select one of the values mentioned above. If the Rig Manager is not running ecerything is working fine like always.
Actual running Rig Manger 1.0.52 Release and KPA OS 2.4.0 PB.

Anybody else discovered this bug?

Thanks in advance Don for your support.
And a very big thanks for the extra points. When do I get the new fridge???
