The path of a tv show source has always to be a path that contains tv show folders. If you want add a source that contains only one tv show you have the set the source settings to "contains only one tv show" and select the tv show path as source.

Thanks for the note. The reason I add the individual TV folders is that I use Plex as my front end and often will just drop individual shows into my main TV folder either for myself or for someone who has a log in to my server. That way, Plex picks them up and adds
to its library, but Ember doesn't see them.

Your note makes sense, but all of my TV sources have the "contains only one TV show" option greyed out. Any idea why?

Thanks again!

You can't change that option if the source is already created (safety and database reasons). You have to remove the source and re-add it with correct options.
