OK, on the pin thing, i was going by your PCB screen print which is incorrect.
Its a bit hard to trace out your board traces and without a schematic for your board and your relay board, it is a bit hard to see exactly what is going on here. By the description of your problem, I still think it is a reference issue to do with you inverted logic.
