One of the films I have in my collection shows the wrong year in the collection (which auto-dates from TMDB)

The film is Licence to Kill [https://www.themoviedb.org/movie/48733-license-to-kill/], which should read 1984 but actually reads 1986.

Checking the release information, it states: 10/01/1984 TV CBS

Is there a reason why that isn't filtering through to the main release date? The only date with 1986 is against an international translation to Swedish.
