I just set up a new digital platinum set. Both of the lane changers do not seem to be functioning properly. If a car changes lanes on one of the lane change tracks, when it reaches the next lane change piece, it switches again whether the lane change button is pressed or not. I am unable to run a complete loop around the track in the same lane. It seems as if the flipper is not resetting. Anyone else have a similar experience, or any ideas for addressing?
