EV Charging Station shows wrong battery data

We have a Multiplus II 3000 GX, Pylontech 48V batteries and a Victron EV Chargingg Station.

Since some time the EV charger shows wrong battery data. Its always 100% full an a 12V system according to the EV charger. On the GX menu and the VRP Portal all Data are correct. How do these components communicate with each other?
