Excessive flarm warning on Oudie 2

I have a flarmcore connected to an LXNAV Flarmview 2 and an Oudie 2. When I thermal with another Flarm glider, the Flarmview alerts me to its presence and then stays quiet. The Oudie 2 makes a continuous aural alert and displays a red traffic warning. It will not stop. The only solution I have found is to disable the audio warning. Then I can ignore it. The Flarmview 2 gives appropriate elevated warnings when a collision course seems possible. It works as I assume it should.

Any idea of a setting that should be tweaked to make the Oudie behave like the Flarmview? FWIW, the last two flights are the first ones I have noticed this problem. In both flights I was flying with the same pilot in the thermal. He has flarm, but no transponder. In both cases, I disabled the audio warning on the Oudie.

Thanks,
