Ghost program on WFM - RSPduo

Hi buddies,
I have an issue when tuned to 88.1 FM (+ some other frequencies) where I hear a station actually transmitting on 103.9 (their 0.1 kW TX is about 1km from home, -31dBm). Switching from LIF to ZIF, using decimation, adjusting manually the AGC does not help.
Lowering the RF Gain of course makes this harmonic disappear but I then I can not hear the "real" (weak) station on 88.1 because of lack of gain ...
No such problem using another well-known SDR.
How can I fix it ?
Thanks for the precious support.
