Cerbo GX shows charging power as AC load

Hi,
I have the following system:

  • MultiPlus II 5000 with Cerbo GX
  • 16 KWh LiFePo battery with Daly. Integrated into Cerbo via dbus-serialbattery
  • SmartShunt
  • Solar inverter from SMA, integrated via venus-os_dbus-mqtt-pv
  • Shelly Pro 3EM as grid meter, integrated via dbus-shelly-pro-3em-smartmeter

A few days ago there was a sunny day and we got so much solar power that the battery was loaded and the power consumption of my house was fully covered by solar. There was even some feedin to the grid.

What bugs me is how Cerbo GX displays this:
It seems like the AC Load contains the power that the MultiPlus uses for charging the battery. On the following screenshot, you can see that AC Load is 3704 W, where I would expect
4732 W solar - 2992 W charging - 390 W feedin = 1350 W

Is this normal behaviour or is there a possibility to change it?

You are using unsupported mods for both your battery and meter, in a supported, correctly configured environment, it would not display this way, but when you run mods unexpected behaviour can happen.
