Might be your DCS config setting of:
 
	options.graphics.stereo_mode_use_shared_parser = true
 
	 
 
	Change that to false and it should render in both eyes.  
 
	This option is still a WIP so weird things happen.
 
	When I know I'm flying at night, I change it to false.  Other then that, I leave it on true.
 
	 
 
	Hope this helps
