Diversions

Yesterday when I was at my local airport (TYR), I saw about 6 American Eagle flights en route to DFW divert to Tyler due to weather over an hour or so. They never appeared as either “En Route” or “Arrivals” on FlightAware. However, they did appear as 'Departures" later the evening when DFW cleared up. Any ideas as to why the arrival information was missing?

The flightplan was likely never amended to have KTYR as the destination.
