Sifa In Hrr

I noticed a wierd thing with the BR425 and 422 in HRR. The Sifa switch can be turned on but the keyboard shortcut "Q" doesn't work when it comes to sifa reset. it works in other routes. Does anybody else having the same problem?

 

I have the same problem when driving BR422 on Köln-Aachen service mode

 

This is a known bug for these trains. Get out of the driver seat and sit back down again and it will work properly
