Worse reception with SDR console 2274

Hi, I also posted this on facebook:
SDRPlay and SDRConsole build 2274 question.
Hi, I installed the newer build 2274, running Win10 on an I7 with 16 GB ram. I do notice that the stop start when switching bands in not longer necessary and that's great news. I do however have a problem with the gain (settings). Some of the gain reduction settings (10 dB, 15 dB) remove the signal completely, where 20 dB or 5 dB shows the signal again. The visual gain has influence on the signal strenght. If I change the visual game, which I assume has only to add to the signal that it's high enough to show in the waterfall, then the S meter readout lowers for the same amount. So, visual gain from 25 to 0 "costs me" 4 S point on the S meter,
I also notice a big lot of loss in the USH 401 - 406 MHz band. With the Airspy and the SDR Play connected to the same antenna, where the SDR play is bandpass filtered and pre-amped at 403 MHz the Airspy gives me a solid S9 (without preamp) and the SDR play gives me S6. If I exchange the receivers and have the Airspy connected to the preamp output the signal rises from S9 to S9 + 10 and the SDR play without preamp drops about S3. Does anyone else have this experience ?
I have switched to HDSDR for a moment and with the SDR play and preamp the signal is now S9 +30 (Logper pointed at a radiosonde at 15 km height and 100 km away)
Kind regards,
