Consumed AmpHours (JKBMS) via Modbus always 0

Hi there, I am using my JK-BMS with my VernusOS(Rasp). The remote console of my venusOS shows me the device SerialBattery and within there I can see the BMS values correctly. Also in the VRM Portal I can see the values like the Consumed AmpHours. Even with the ssh command dbus-spy I can see the Con.AmH value...

But If I try to read this value using the register 845 (com.victronenergy.system) or 265 (com.victronenergy.battery) , it is always zero ...

Does anyone have an idea why the value is not exported through modbus?

No one can help me out here?

I think it does not have anything todo with my JKBMS because the valie of ConsumedAmphours is entered in Dc/Battery/ConsumedAmphours correctly ( as I can see in dbus-spy) but not transported over modbus ... the query returns always 0 ...

Can I provide by my self values maybe using a config file inside venus OS?
