Metadata Issue (Anime)

[Konsi]

For the record, the fact that manually adding an NFO resolved the issue tells me that the show was added to your library under a different show name (misidentified).  But, again, this is a hypothesis based on the information available.

Not quiet right. The show were added so or so it just the Metadata that did not load. 

Example : I created a Folder on my GDrive with the name Dead Mount Death Play and added episodes
It will show on Jellyfin a Folder without any picture or most of time the first scene of the first episode u uploaded, no Metadata information, no Orginal Picture, No Background just basically nothing organized its just a Folder with Episodes on it and the Episodes are named like u named them not the real Episode name.
