Hello. I have a question regarding the ball release feature on a Stern Viper. Scenario: a ball or two are locked for multiball and ball three drains prior to getting a multiball. Is it a normal feature that those balls remain locked at the beginning of the next game or should they all release prior to the start of the next game? I have read the manual and can't seem to find anything that I could change to allow those locked balls to drain prior to starting a new game. Any help would be appreciated. Thank you.
