I recently replaced my drop targets in my Bally Special Force and since putting them in, the two single drop targets like to randomly fall on their own without contact. It usually happens when the ball is in the pop bumpers and it seems like the vibrations from them is causing the drop targets to fall by them selves. This was my first time reaplcing drop targets and I wasn't sure if there was some sort of location adjustment that needs to be made. They still register properly and work properly, they just like to randomly fall on their own. If anyone has any advice on how to stop this issue that would be awesome.
