You’re right, this doesn’t make sense. I just double checked the LED numbers and you were correct, I had read these the wrong way around… here’s what we actually have:

When Blue D45 is ON, Red D410 and D105 are ON
When Blue D16 is ON, Red 111 and 106 are ON
When Blue 42 is ON, Red D102 and Red D410 are ON

Do you know from this what’s going wrong?

Thanks so very much for your patience with this (and me!)
