Strange MLAT track logs (someone feeding MLAT as ADS-B?)

FlightAware ADS-B Flight Tracking

So i’ve checked some tracklogs of planes i see via MLAT.

Strangely it often states an ADS-B source, but it’s always a source from ZRH.

See for example this track log: Flight Track Log ✈ KLM1647 13-Sep-2018 (AMS / EHAM-FLR / LIRQ) - FlightAware

It’s not really a problem for me just wondering :slight_smile:
