Recently my 1st drop target in the right side GNR bank hasn’t been resetting properly every time . Mechanically all seems fine but the far left target won’t always stay up when the ball drains or I begin a new game. Sometimes it does and sometimes it does not. i’ve attached a video below. Manually with the play field up it appears to move freely with out binding up and down just like the other 2 . Any suggestions ? This video is 4 seconds and is right as the ball has drained and the next ball it kicked up into play . Thanks
