Having a problem with a new AC/DC vault, the ball gets stuck on the 3 AXE lanes up top. It's not the switch, you can see the ball rolls over the switch and then gets stuck on where the slot is routed out in the wood playfield. I don't want to start filing anything so thought I wold ask here if this is common and if there is a fix. I have to raise the back legs up really too high to get it to stop and would rather not have to do this, makes the game too fast. TIA
