Try it with 2018, like @anon18523487. Plex Dance the movie after changing the name, to clear the bad metadata out of your Plex Server database.
This might be one of those weird cases that crop up every now and then.
Revenge, the movie you want, shows in IMDB as Revenge (2017). It was shown at film festivals in 2017, but the official US release date was 11 May 2018.
Higanti, the film you don’t want, shows in IMDB as Revenge (2016). It was shown at a film festival in 2016, but the official release date was 22 March 2017.
That could be the reason for the mismatch and appearing in Plex with a different year.
