High negative House-Load and Feed-In shown instead of Consumption - only when EV Charger / Wallbox is used

Hello everybody
just got our brand new FOX system installed but something seems strange....
A very high negative House-Load and a positive Feed-In shown instead of Consumption - only when EV Charger / Wallbox is used.
When not charging the car, the system shows reasonable figures:
When charging the car, the system shows a very high negative load on the house, and it keeps showing Feed-In, even though I actually consume a lot from the Grid then:
Photo of the GRID Meter (provided by the Electricity Company) showing that I actually consume energy from GRID
Photo of the first Meter (after which the Wallbox is installed) showing the same consumption as the GRID Meter
Photo of the second Meter (after which the Inverter is installed) showing the Power which the Inverter provides (and think's it is Feed-In) ??
Photo of the Inverter Power display:
This is how the install looks like:
GRID
> GRID Meter (official)
> FOX Wallbox Meter >> Wallbox tap-off here
> manual EPS Switch (set to GRID)
> FOX Inverter Meter >> House tap-off here
> FOX ESS H3 8.0E Inverter (Grid socket, and here also the House is connected).
Why is this showing so wrong? Is the sequence not correctly installed or is there something wrongly configured?
Also, I think when I switch to EPS power, off Grid, the (second) Pv Meter gets fed by the EPS power and provides data to the Inverter.
Shouldn't in an EPS case, the PV SmartMeter be off and not send any data to the Inverter?
Sorry for so many questions and thanks for your support.
