Master not Switching for live Show

Master input works fine, scheduling a show with uploaded content works, but if a dj trys to connect to live input, the stream switches from master to show for a sec then goes back to playing the master, the only way i could get it to work is by manually stopping the master stream and then the live stream worked.

This is a clean install and  i followed the instructions in the manual and did a automatic install, maybe i missed something ?
