Foreign movies: movie and poster not found

Hello,

I own english movies and foreign movies. What I would like: if I have a french movie, the path of the movie contains the french name and the poster will be also in french.
I don't know if it can work like that. Some movies are detected, some not and for other I can't get the poster in french. My scrapper is the following:

Scrapper: the movie database

Settings:

Keep original title: on
Enable Fanart: on
Enable Trailer: on
Preferred language: en
Preferred certification country: us
Defaut rating from: Imdb
Add also Imdb rating: off

Content and scanning options:

Movies are in separate folders that match the movie title: off
Scan recursively: on
Exclude path from library updates: off

I have rescan my library, but I had to cut the log file, because it was to big. I hope I didn't cut some important information. The
log is: https://pastebin.com/qq8P9EcU

There are two cases:

1. The movie "Back to Burgundy". The path contains the title in french: "Ce qui nous lie". Movie db: https://www.themoviedb.org/movie/432087-...uage=de-DE

The original title is the french title. The poster is found un kodi but it is  in english. If I try to change the Poster, I can't find a french version in kodi, but there are several version on the database.
How can I get the french version ?

2. The movie "Do not Disturb". The path contains the title in french: "Une heure de tranquilité". Movie db: https://www.themoviedb.org/movie/298614-une-heure-de-tranquillit?language=de-DE
The original title is the french title and it exists. Kodi don't find the movie. Perhaps it as to do with the "é".

I want to keep the language "english" because for a lot of movies it's perfectly ok.

Thank you for your help!
