I have my API in Kodi setup in english (US), but KODI know that i am localised in FR.
Thanks

When you say My API, are you referring to a program you developed or created?
Or is it a third-party developed Kodi Addon or Plug-in that you installed on Kodi?

Ok my bad, i was indeed unclear. I use MovieDB scrapper in Kodi, nothing special.

Why do I need to write the title with 1999 to get it scrapped correctely with 1997 ?

What movie are you talking about?
Can you tell what is the title or ID of the movie?
When you search using the correct year, 1997, the data does not appear?

Have you ever asked about this issue on the TheMovieDB Scraper Forum?

Is this problem occurring just now? Before it did not occur?
Or is it just happening with a specific movie?

But the problem is now solved (maybe it has been corrected since my first attempt) . Thank you for your patience.
