VRM dashboard showing weing (outdated) values

howdy,
yesterday I turned off my charger (Quattro) and today the VRM dashboard still shows the last values as of prior to turning off the charger.
Turning off means the Quattro is in off position and grid power is cut as well. No other charger (yet)
System is on a Cerbo GX MK2, fw 3.60

Any ideas ?

Thanks
Oskar
