Why is No Track Shown?

I completed an IFR flight 14 hours ago in N751PP, but no track shows. What’s up with that?

If you look closely, there are two postion reports just west of SBA. Perhaps ATC closed then reactivated the flightplan just prior to arrival.

Thanks. I see a data point at 5:19 and then one at 5:20, both when I was near the end of an ILS. Do those mean that those were the ending times of the flight, and that that 1 minute flight is the only one with the track? Makes sense, I guess. I’m glad the flight dropped out of the system, and not my flight out of the sky.
