Why does aircraft sometimes jump?

[Kpin]

I observed this very strange behavior:
Jump.JPG
It happens at the very end of a flight to Napier in New Zealand (NPE/NZNR). The place is rather remote and only covered by one receiver T-NZNR1.
When the aircraft has landed it jump to a position about 60-70 kilometers to the west. It seems like only the longtitude is affected.

The route is operated by only two aircraft ZK-MVA and ZK-MVB and the same behavior is not seen when they fly to other distinations.

I understand that the receiver most likely lost contact with the flight after touchdown, but why this jump. I have seen it a number of times.

I got a feeling his receiver or SW is providing bad data. Not sure he/she is a forum member either to let them adjust the sensitivity setting either

I suspect he's using adsbScope which doesn't handle on-ground messages correctly.

I have just joined the Forum. I have ordered the gear to become a spotter. Hope I can work out how to set it up. I am 2.54 NM south of the centre of Napier runway. My antenna will be approx 9 m above sea level. Yes these Napier aircraft dance all around the sky like crabs.
