FF v6.2 tracking aircraft on ground?

Does the 6.2 version of the FF software now track aircraft on the ground? I now occasionally notice some aircraft on the local page without lat/long markers and at 0 ft altitude moving slowly. However, they do not appear on the FA website. Or ar these error messages?

At some airports in the US, at least, ground vehicles are transmitting ADS-B location data. KLAX is an example, as is KSFO.

I tracked these on VRS and they are indeed aircraft on the ground they are also showing on the stats page

Yes it does.
