There's an issue with the 100 point score reel for player 1. The game was repeatedly advancing the reel, so I turned it off. Upon turning it back on and starting a new game, the machine wasn't able to reset that reel back to zero, but it kept trying.

Hit the spinner, then the score reel continued after it stopped Only stopped after a couple of other switch hits

New game, score reset to 00,090 instead of zero. Not a big deal now, but severe for tournaments
