It also seems strange that the two Hex Codes are both bringing up two different Aircraft Registrations.
You must make sure that both your transponder and PilotAware are properly configured with the correct registration and ICAO Hex Code for the individual aircraft they are fitted in so that PilotAware can properly filter out your own aircraft.
PilotAware also has an option to record multiple configuration profiles to allow it to be used in more than one aircraft, but you
MUST manually select the correct profile before flight.
