sources is only one part of setting up content in Kodi.
You need to do it on a full client first.
That will add the correct scraper entries into the movie database

There is no way to do the "set content" on headless.
That actually stores info in the DB about the scraper settings etc etc

Get it the DB / sources etc all working with a full client.
Then copy that to headless

Headless Kodi != Server Kodi
Its just another client that can run without showing a GUI
