Same for me, and my native tongue is also French. My aTV is setup in French, but Infuse is configured to get metadata and subtitles in English. This started yesterday with the new update, and the change of database for metadata. Everything worked fine before.
Ex.: I have NCIS episodes, in English.
NCIS/Season 1/1x01.mp4 etc.
Now in Infuse, under NCIS, I only have one folder, called Specials, with all the files, and metadata is the same for each file. Consequently, trckr.tv “mark as read” doesn’t work as intended anymore either.
Same happens with Quantico, under the same naming system.
This is related to TMDb, I am positive, as before this update, everything worked as intended.
My only work around for now has been to disable metadata fetching, delete current metadata, and to switch to list mode (all of this sucks, for a paid software).
