Problems with AXS / Flight-Attendant System

I use the Karoo on 2 bikes with AXS. Everything is cool on my gravel, 2 controllers, rear derailleur and reverb are displayed.

On my MTB, this was the same with the "old" AXS. There I was also able to make the 2nd. Set the button of the left POD for the Karoo.

Now I have converted to Transmission and Flight Attendant. Now the Karoo only shows me a controller (the left one), the rear derailleur and the reverb. The second controller is missing and also the Flight Attendant!

It would also be great if there was a data field for Flight Attendant, which shows me the current status. My fork crown is exactly behind the handlebars and is not visible to me while driving.
