This is due to PCAS (mode C) collision alarm. The same issue exist in other flight computers like LX9000. You need to turn off the Mode C alarm option, and leave only the alert (new traffic alert) option. Each flight computer calls it differently and I am not familiar with how SeeYou calls it so you may need to poke around and find how to disable it correctly.

Ramy, would it be a mode C alarm if the glider setting off the alarm has no transponder?

Also, I'm not aware of a way to change settings like this separately in the flarm view and the oudie. I thought the configuration was globally set to the Flarmcore via the configuration file.
