Hope this is an appropriate forum for this question (this didn't seem to fit neatly into any of the aviation-related forums).   

I've noticed many times on the Flightaware flight activity/tracking screen for my home airport, that certain flights (and it seems to be random) will sometimes display multiple times. It's always in the Scheduled Arrivals or Scheduled Departures sections. Sometimes none of the flights are repeated, and sometimes one will be, or more than one will be, and that then crowds out other scheduled flights.

For instance (not sure if I can paste a screen print on these posts), in Scheduled Departures for today, there are 2 separate DL flights listed like that (one listed twice, the other listed 3 times). Is anyone here familiar enough with Flightaware's flight tracker to know what causes this, or if there's anything on my end I can do to avoid/correct it?

Thx!
