I think it tries to set it to the current route it’s on and it overrides all the other options except for “closed” and blank
I just got this, but in my limited exploration PIS on AI trains is not working at all. Either it's blank, or it reads Geschlossen/Bitte nicht einsteigen (closed/please do not board)
Yea, there seems to be multiple different issues with it, in many cases resulting in the system as a whole displaying blank or nicht Einsteigen for one reason or another
