Tracking for VFR flight following?

After doing a little flying last Sunday, I noticed that flighaware had my flight listed at

It was a short VFR flight to drop a guy back at his airport and I’d called to get get Class C service for the trip down from PWA to 1K4 just out of habit. On the return flight I picked up radar service again to do a series of practice approaches to OKC and PWA but that flight is not shown on flightaware.

There is no track information shown for the leg that appears on FA, but it is odd that it even appears in the system. I get radar service or flight following from PWA tower all the time and nothing ever appears on FA.

Any thoughts?

Sometimes it happens; we think it depends on the way the controller enters you in to the computer.
