RW on the shifter has a fault on the pcb, I fitted a bodge wire from pin 9 on IO port 1 to pin 31 on the shifter and were all up and running, so no wonder things were confused.
@PhilC - That RW route to the shifter comes from IC6 and is where FIX #2 is required. Is there a possibaility the RW line got damaged during the fix or is it a quality issue on the board? The RW route is on the bottom layer so you should be able to see any damage.
