Firehawk FX changes gain/level after engaging the tuner function

I noticed that after having the built-in tuner engaged, the level was in some cases noticably lower than it was before the tuning. I found it can be reproduced by rebooting the unit, after the first time to use the tuner, the level is reduced. I hooked it up to a mac with SSL12 soundcard and Logic, ran a 1kHz test tone to the Guitar input and recorded it back from the left tele output jack (making sure the routing was correct so there was no electrical feedback). The RMS level difference was around 11.3 dB in one case, for a patch that I call "Bypass" because there are no effects nor cab simulator turned on in the signal path. The same issue occured for both settings of the output mode (Line/Amp). I did not observe any change of the red/white volume indicators around the big knob. I have version 1.30.00 of the firmware. If anyone else has a good and safe workaround it would be nice to know. The best thing would be a new firmware though. (Screenshot image showing level before and after engaging the tuner, it's muted while tuning.)
