who can explain the weird time of charge log of MFM

[modeler]

Very strange. MFM always says a charge log different from what actually should be.

example, I start charge from Saturday night, it says charge
it says charge from Sunday 4:43AM- 8:39AM
and I know I had a short trip of 30km and back 930 AM.
it says charge from 12:56PMSunday- 9:03PM

It seems the starting time of charge never correct

It doesn't seem to be recording properly charge start time. Charge end is OK
