DrivenByMoss: Bitwig extension for many hardware controllers (version 26.6.2)

[Tj Shredder]

Hi, I have a problem with the Mackie script which should work with a Behringer XTouch One. As I have other faders for all the channels (Console 1), I just want it to control my Master Fader. I switch on Master on the device, and it actually does control the Master fader in Bitwig, but after a second or so, the motor fader on the device jumps back to zero. It should stay in the position of the master in Bitwig. Also moving the master in Bitwig does not move the fader of the device.
I wonder what I am doing wrong...
Is there a secret setting I am overlooking?
I am on Mac Sequoia and latest Bitwig 6...
