Not a big deal, and once you know what the buttons do, you'll never have a problem but...
The mix recall buttons aren't very intuitive. My first inclination was to hit the camera button to save a snapshot of the current mix as something. Obviously, that wasn't the correct button. It looks like the button images are bass ackward for people using the program without RTFM, the snapshot button saves the current mix to the current file, the document like button is save as. As a complete idiot and neophyte, I would expect the meanings to be reversed.
P.S. I'm glad there is an option to save the selected track settings, perfect for what I want to use the feature for.
