Steam Mp15dc Brake Issue

There seems to be an issue with the braking on the MP15DC. The brake controls aren't working correctly. The cut-in knob only releases the Indy brake on "passenger" setting. Even the the trainline brakes don't work on that setting

 

Have you set it to lead and dead?

 

yes no change. It works when using it on TSW3. I believe it got bugged in the changover
