I have PC lap counter working with my SCX Digital track. I am experiencing a weird issue where the lead car is counting two laps each time it goes past the start/finish line. All other cars only appear to be adding one lap at a time. What seems to be happening is once the lead car cross the start/finish line it will add a lap as normal and then within a couple of seconds it counts another lap. What is really weird is that this only appears to be the lead car. Any ideas if this is a PC Lap counter issue? I have tried swapping out different SCX Digital control units (standard and Pit Box DCU's) and swapped the Start/finish track and the problem is still there so that leads me to believe it is the software rather than the track or cars.
