There are some duplicate flights getting listed for Level flights operated by OpenSkies - for example, today your system has BOS9 (OpenSkies) and LBC8009 (Albanian) listed as two different flights, but, it’s the same flight.
I suspect this issue might be tied to the fact that BOS and LBC are both associated with the IATA code LV. LBC/LV/Albanian has been defunct for a while though.
Thanks!
