Quoted from crwjumper:
I have a possible factory wiring anomaly - when slightly pushing the right flipper button, the top flipper fires, and then when depressing it more the bottom one fires. Is this how this is supposed to be on this pin? On any other multi-flipper pin I've had, the bottom flipper fires first so you can cradle balls while still being able to use the top flipper. Please test yours and let me know. Thanks!
Nope, should be the other way round, lower first then upper.
It will be an easy fix but if I were you I'd contact JJP or the distributor to ask them (before you make any wiring changes).
