The Battery SOC widget (source: Battery Monitor) no longer displays data in VRM

Hello!

For an undetermined period of time (but no more than a few weeks), the Battery SOC widget (from the Battery Monitor source) in VRM (Advanced tab) has been displaying ‘no data to display’, even though it had been displaying the data correctly since the installation began. I had to configure the “System - Battery SOC” widget, which displays the data correctly. But why does the Battery source no longer display this value? Other Battery Monitor widgets work perfectly (“BMS Min/Max Cell Voltage”, " Battery Temperature Sensor", “Battery Summary”, etc.).

My setup: Pylontech US2000C + Cerbo GX + Inverter-RS 48/6000/100

Thank you.
