There was a headwind, but it didn't seem THAT bad

This was for a flight from SYI (Shelbyville, TN, a great airport to visit if you’re in the area) to RVS (Tulsa, OK Jones).

What the heck is that smear in the flight track to the southeast?

Also, I had to miss at RVS and went on to RQO (El Reno, OK, west of OKC), but that part of the flight doesn’t appear. Why does the flight get cut off after RVS? I shot the approach to minimums but never left the system (although I did go from Approach to Tower and back).

Someone else was flying with the same tail number, likely by mistake, so a few position reports were generated for somewhere a few hundred miles away.
