In a couple of machines I have the same problem on some drop targets. These drop targets are supposed to be hit (one ore more times) until they drop, and then they will not come up again (for some time). When the drop targets are up and they are hit, the ball is supposed to bounce back. But my problem is that when the ball hit the targets, the ball does not bounce back, but makes the target to fall and moves directly after them. Basically the ball run through the targets, instead of hitting, making them dropping, and bounce back.

What to do?
