VTX data not saved

[zpust00]

Running HDzero freestyle V1 vtx. When i save (under Configuration tab) the vtx settings are shown as saved. But when i power the drone (7inch) up, are set to Boscam A, channel 3. (I use raceband, with channel 1, power 1). Is this my problem or does somebody else have it too? (My first inav project.)
