Mixer and Edit open one on top of each on the right monitor no matter what I do or even saving new "Windows Configuration" I'm on Sierra also.
I've created a new session and still the same problem.

I know this isn't really what the OP was asking about, but another user mentioned that with dual monitors, if you Option-click the green button at the top left of the Mix or Edit windows, it should maximize the window and retain the setting next time the session is opened. It works for me on Catalina.
