Solax X1-AC-3.8

Hi,
I'm playing with switching between the 3 of the 4 modes of force charge, period 1, period 2 or neither.
Period 1 being my cheap rate overnight, period 2 set to all day. Then if my rate drops(octopus intelligent go) during the day I can charge my batteries rather than flatten them by charging the car.

I can up date the times for period 1 and 2 and they set successfully but when I try to change from both allowed to any other option it reverts back to both allowed. I've locked and unlocked the inverter to make sure that wasn't the issue. Anyone got any other ideas?
