Total wattage on two of the circuits was just 1 recessed LED (max 10w I think). The other had two of those LEDs. I can see through the cracks on the side of the switch and can see that the board is labeled the same as the case. I can’t explain it, but changing the line and load made the difference.
@fdi3260 - Funny video. I’m surprised someone can shock themselves that much and then bust out some circuit diagrams. In this case I was replacing a GE/ Jasco switch. So I really don’t think it was the lights or wiring.
