Quattro 3kva power and amps are not showing

Hi i am using Quattro inverter, the power and amps are not showing. i have 6 units and 2 of them are not showing .Can you guide me why or how to solve it.

Is it 3 phase with 2 in parallel on each phase or 6 in parallel?

I have six units in total. they are separate, not connected together

Ok. So just 2 individuals are not reading correctly?

Can you update their and change their settings etc as per normal? And functioning normally otherwise?

yes correctly.

update firm version? yes rest is working fine
