@dbirch gave excellent advice.
You might also try the Plex Dance and before putting it back into your library, rename your Fear the Walking Dead folder to include the TMDB reference and year (see the naming article from dbirch above). So for that one you’d do \TV Shows\Fear the Walking Dead (2015) {tmbd-62286} and that should help force a match for it. The number comes from the URL for the show at TMDB: /tv/62286-fear-the-walking-dead
