Brent, That is strange looking for sure. You need to send that pic over to Doug and let him see it. The mod descriptions on Oade's site indicate the headroom is extended with the concert and warm mods, so I can't imagine how this could have happened with the -18db attenuator engaged also. Did you go back to the XLR preset and double check the -18db setting was still set afterwards?
The reason I ask is when I first got mine, I thoought I had the settings a certain way, but I actually failed to store the preset selections correctly, and only realized it later on when I checked it again.
