Qantas Flights Show As Qantas Link

On FlightAware, when you search a Qantas domestic flight it is listed as a Qantas Link (QLK) until the day of departure and it seems to be as late as when the flight plan is filed. It then changes to Qantas (QFA). Any idea why QF would do this? Might be a sceptical view but is it something to do with delay stats?

This bug has been fixed and the scheduled flights as well as enroute and previous flights will appear as QF or QFA
