What brand of transponder are you using? Trig? If so, you’ll want to check what code is in the transponder. Not the 1202 VFR glider code, but your assigned aircraft code.

Go to the following link and start on page 29. Hold down the Fn button when you turn on your transponder and it will go into setup mode. Use the ENT button to move forward through the options. #2 should be the ICAO code and this should match what the FAA has assigned you and what is in your Flarm config file.
