Steam Spirt Of Steam Prepare Scenario Bug

so on all the spirt of steam's preparing train scenario with the LMS jubilee. Its from you get out from a siding, turntable, get out from the sidings and going to the track where youre suppose to be backing up to your train. Then there the red light doesnt change at all and youre stuck forever.
Or am i doing something wrong???


DTG please fix this.

 

Did you ask the signaller to pass the signal?
