I am new to pin side. I have been working on my Jacks Open and I have a problem that I need assistance with. When I get to the “special” royal flush, the drop targets continues to cycle and does not raise the drop targets. It will cycle non stop until I turn off the machine. I also sometimes have intermittent problems with first four “zones”, (2 Jacks, 3 Queens, Full House, Royal Flush). Any assistance is greatly appreciated!
