Cubase 13: No mirroring of mixer zones to DAW-Controllers in Mackie mode?

I have Cubase Pro 13.021, the MCU pro with 1 extender and a PC with Win10 and latest updates.
The Mackie MCU Pro don’t recognize mixer zones anymore, so you can’t fix for instance your group channels on the right side and have the others on the left, as displayed in Cubase. Not long ago (I think in Cubase 12) this works without any problems. But if I start C11 or 12 now, the same problem occurs. Any others with a similar config do have the same problem or are there any suggestions, why this issue occurs?

Thanx in advance for feedback
