Mine went to sleep and when it woke up both displays are mirrored.
I tried to turn off airplay, unplug, ect, but everytime it comes back it shows up as a mirrored monitor, even though the system THINKS there is a second monitor (mouse travels past edge of screen).

I'm getting the same thing. I can't get the DisplayLink screen to work in extended mode. Even when AirPlay says it's being extended, it only displays what is on the primary screen.
