GLM 4.1 - Wrong Microphone dBSPL Level

Hi, I just installed the GLM 4.1. The AutoCal 2 seems really better than the AutoCal1. But maybe it's just on my system, but the microphone dBSPL reading seems wrong. I'm at about 69 dBSPL when the room is quiet, it was never like that before. When i start an autocal process, there's a warning that my noise floor is to high. I'm pretty sure my noise floor is not at 69-70dBSPL so maybe a bug here.

mine did the same thing. resting dbspl is like 55db, but when I went to calibrate it said the spl was 65 and the 'noise floor was too high'. i calibrated anyway, but not sure i like the results.

Also had the "high noise-floor" warning in one calibration in a rather silent room. Another one went fine.
