Why does the MAP function not seem to work properly on the A319/320?

Every flight I've taken recently on those aircraft (quite a few unfortunately) has the map showing wrong information...ie: my 0700 departure from YEG-YYZ shows an arrival time of 2050, along with other incorrect data points.

I've had the same thing on some WB but less frequent...I recently was on a 777 from YVR - YYZ and the IFE MAP showed that the flight had originated in YQR...now that would be a serious IRROPS!!
