can see the feed (lyrics) in Properties for NDI Source but not in preview or program.
I can't send the ndi source from ProPresenter 7 as a camera, not sure what you mean by "using the networking as your "video device."In my experience, I had to use "Video Capture Device" whenever I was using NDI's tools. I used NDI in order to get lyrics into Ecam Live (very similar to OBS), so I know there is a way to do it. Try adding it as a camera input and using the networking as your "video device."
