Axpert MEX 1.5kVA 12v not showing battery discharge current and load power

I just purchased a brand new Axpert MEX Series 1.5kVA 12v inverter (branded Mecer) it's producing power but if I put a load on it and scroll down the screen I see 0A 0W 0VA on the inverter. It's strange because on my digital clamp meter reading that measures DC current I get around 7.2A discharge from the battery.

 

Is this normal for this inverter?

I don't know the 12 V models, but that certainly doesn't seem right to me.

It is showing 230 V output? Does it actually power the load?

I assume it must be yes to both the above, since that 91 W has to go somewhere, and most of it should end up in the load.

Yes, it's powering up the loads. I get 230v at the output. According to the user manual it should show the load percentage , load power in watts (W) and volts amperes (VA) and battery discharge current to my surprise all of the aforementioned show 0.

Looks like for it to show the information the load had to be higher than 10% , I tried with a bigger load and the inverter started showing the load percentage, load power in watts and volts amperes and battery discharge current.
