My JM seems to have some glitch and I'm wondering how to resolve it. This only happens after I drop the 2nd ball in the matrix.

After I drop ball #2, the machine will auto launch ball #3. Problem is that it also launches ball #4 immediately after - causing me to believe I'm playing 2 ball multi-ball but I don't think that's correct and here's why. If I shoot one of the balls up the middle and into the VUK for the glove, it will automatically drop that ball over and over again, as I'm playing the second ball on the playfield.

If I loose the second ball, it will continue cycling the first ball between up into the glove and drop back down continually....until I turn the machine off.

If I lose 1 ball during this time, it acts normal and goes to load another ball (assuming this wasn't my 3rd ball) - problem is that it will launch both balls again

Questions / comments:
1.) Is this normal to JM? This is my first time owning this game
2.) Only happens after 2 ball is locked/loading into the 3x3 matrix
3.) Continues with 2 balls at every launch for the rest of the game
4.) Glove goes into infinite magnet power on/off cycle until game is turned off
5.) If you never lock 2 balls into the matrix, you're lead to believe everything else is working fine
6.) How do I go about resolving this?
