Our Kiss Pro recently started kicking out two balls randomly to start game play. Happens once every 10-15 times. I hear the coil eject, then it ejects again. Almost as though it didn't think a ball came out, but now there's two balls in the shooter lane. I've had to reseat the optos on my AC/DC Prem when there were issues, but I'm unfamiliar with the new Spike System. Any one have something similar happen with a Spike (GOT, KISS, WWE)? Am I missing something obvious? Any thoughts?
