Steam Br 185.2 Change Cab Issue (vorarlberg)

Greetings to all!
I encountered the following problem - when changing the cabin to DB BR 185.2, the signal lights in the other cabin do not turn on and the AFB does not work. If you go back to the other cabin, the AFB and lights works again. Is this a bug, or am I doing something wrong? Maybe there are instructions on how to properly change the cabin?

 

Yeah i think this is a already written bug.... But it could be that im wrong....

 

I searched the forum, but didn't find a similar case, so I thought maybe I was doing something wrong

 

Oh okay what did you before changing ends in steps?

 

I tried different options, starting from the simplest - put the brake handle in full service, the controller in the off position, the reverse handle in the off position and pull it out, and then in the reverse order in another cabin. I also tried lowering the pantograph and turning off the battery - the result was the same
