I noticed that the last two episodes from The Grand Tour (2016) are named for the show itself. Thetvdb, TMDB and IMDB all list them (epi 9 and 10) by the title, respective “Breaking, Badly” and “Oh Canada”. Trakt sees I’m watching “Oh Canada”, so everyone knows the title. Just Infuse says “The Grand Tour (2016)”.
As far as I know these are the libraries you search in.
Any idea as to why the unknown (??) metadata comes up?
