If the Outhole switch diode is bad, it could trigger multi switch registrations.
Put a crisp $100 bill between the contacts on the outhole switch, gently pinch the contacts together, and draw the bill through until it comes out clean.
1/16" gap is plenty for the switch with no ball in the hole.
Tug on diode, make sure it's not broken.
In switch test mode, test with a ball, NOT YOUR FINGER.
