Question about naming of Movies



Sorry, this MUST be an FAQ but I can’t find an answer …

I have a drive with movies: One folder per Movie, with names and years, for example “A Few Good Men (1992)”. I used to name the folders after the original names from IMDB which always seemed to work fine. I wasn’t using KODI for a few major versions and installed a 21.1.0 (Android) version today. “The Movie Database Python” seems to miss many of my movies, however the log shows only one single movie which failed to get scraped. Shouldn’t it be possible to find al movies which failed to get scraped? 

From the settings of the scraper it seems I can only configure one language, so mixing the languages is probably a bad idea, right? What is the preferred strategy for naming of Movie folders with respect to my native language (German)? Everything in German? Everything in English?
