Feed-in limiting active ... always true

Good morning Community

I’ve a new setup with three Mutiplus2 configured together in an ESS.
My PV is around 6kWp. At the moment the PV can produce around 4kW when the sun is shining.

When my Pytes batteries are full the system should feed in the power to the grid. Up to 4kW.
You see this in my screenshot.

Now the Strange behavior:
The grid feed in is limited to around 1kW when “Limit system feed-in” is on. Even when the setting says 4000W. “Feed-in limiting active” is always yes.
When “Limit system feed-in” is off, everything works as expected. The system feeds in all the unused energy.

Anyone knows why there is this strange behavior with the limit even when it’s below the setpoint.

Thank you,
Martin
