bfd and rew question


I have a strange thing happening. I set up rew and the bfd and did some measurments and just tried to get familiar with the tools. Things seemed to be working out. Then I wanted to experiment and this is what I did. I took the bfd out of the loop. I wanted to start by using my avr's audyssey program as a start and use rew to see what it's doing. It didnt look to bad actually. Then I was going to fine tune with the bfd. So I put the bfd back in and pressed the in/out button(flashing) and assumed I was in bypass mode, straight in-out. I then took another measurement to see if my graphs changed and they did, a lot. But no filters are being applied. Why would this be? My gain messed up maybe, or maybe I didnt calibrate the sound card correctly?

Another odd thing is when I do a measurement and get a graph and then generate a waterfall of it the peaks on each are different? They look similar but the peaks line up at different freq.
