ModbusTCP and Home Assistant cant read register for one MPPT

Don't know if anyone here can help. I have been playing around with HA integration and so far everything seems to be working except i cannot read registers of one on the SmartSolar MPPTs. The setup is exactly the same for the other SmartSolar MPPT, only difference is the unit ID. Is there anyway to change unit ID in Cerbo GX.

Working SmartSolar MPPT.

Circled Should be "Solar Controller 2" which can't be read.

Any Help would be much appreciated
