negative trip distance

Hello,

In my trip report of today, and some other days, there's a trip with a négative distance.. how is it possible?
The odometer end is highter than the odometer start...
Is there a mystake with the data logging system of the device (when the vehicule is ina blind GPRS zone) ?

Best regards.
