How did you add the masts to the panel? Did you use the right click on the turnout and ¡®Set signal masts¡¯ so it knows they are at that spot on the layout. If you just use the Layout Editor menu, that doesn¡¯t ¡®bind¡¯ it to that part of the track. Also you have to watch and make sure you pick the right boundary that the mast is attached. It is easy to get reversed if you don¡¯t read it carefully.
