I very new to pin side. I can't imagine this hasn't been covered. Searching for a solution to my Getaway serving up two balls took me to a lot of discussion of different ROMs, As I never changed ROMS I didn't think it could be my problem. I remembered one time my em Fireball did that and, it turned out to be a switch in the ball trough. I removed the apron hoping it could be a simple switch adjustment or bad switch. It turned out even simpler than a switch. Some how an extra ball had gotten into the machine. Fortunately it still had the label to install 3 balls, I could have chased my tail if not for that label. Removed the extra ball and it is working fine again. BTW I normally don't pay attention to ROM version, Mine is Rev L5.
