DIYBMS data logging

I have a question to the data logging function:
Data logging is enabled and DIYBMS diligently records every 60 seconds.
When I now switch off the BMS, the SOC is not at the last value, but at 100%.
For me it would make sense that the SOC is read from the memory when it is switched on again.

Or I change the hardware and want to copy the setting to the new controller. Unfortunately, there is no corresponding function.
