My flightaware feeder information is like this.
Nearest Airport: Jeju Int’l (Jeju) (RKPC)
Antenna elevation above ground: 3 feet
Ground elevation: 66 feet
Location: (48.11884, 11.52115)

Nearest Airport is right. But… feeder Location is wrong, When i change to correct GPS location 33.51171, 126.49239 then itself will be change to 48.11884, 11.52115 soon. I think this is error. How can I fix it?
