The Live Tracking Page shows different result than flight log?

I was tracking a freinds flight, , on November 16 into KRBD, so I could pick them up. Got to the airport and couldn’t find the plane and the main Live Flight Tracker page with the map had dropped the track along the approach into KRBD and said the plane had landed at 5:53 PM. I actually saw the plane land at the 6:10 PM time that the Flight Track Log lsited. Why the discrepancy between the two pages?

Sometimes at smaller airports the FAA sends us an arrival or cancellation when the flight is handed over to the tower rather than actual wheels down. The track log continues to record positions until the apparent end of the flight.
