I have just had this issue as well, I have 3 displays: Internal Panel (Disabled) 27" on HDMI (Active) 27" on VGA (Active)
I managed to work around the problem by activating the internal panel so it shows all 3 displays then I could drag the displays into the desired layout. Before applying the changes I turned the internal panel off again as I didn't require it but it saved fine.
