Sub 37 Output Level Change since FW1.2

I use my Sub37 live and when I updated the FW to 1.2, I noticed, that it suddenly had about 9dB more Output level. I can only tell this, because the gain parameters on the mixing desk are saved and i compared that to a previous multitrack recording and my signal chain remained completely the same.

Sub37 → TC Distortion Pedal → Lexicon MX200 FX → FNR Audio RNLA Compressor → Radial DI Box → Midas M32

This is nowhere mentioned and I wondered, if someone here experienced the same thing.
