This is how KODI formatted looks like in Plex. Initially after running jav-it for the first time it seems ok with some minor issues like no DVD-ID and actor image. Subsequently running it over the same folder a few times (due to the new updates) many issues came. Titles become missing from the nfo. Some items got additional as the program thought that the trailer were also the actual movie and generate additional nfo fanart etc. The first time I didn't change to preserve original file names and subsequent runs it generates again and preserves files names but includes the previous generated items. Also when partially downloaded files ending with .bc will still be considered as a movie file and the items gets downloaded. After movie file download completed and running a second time the items gets re-downloaded. My local folder are also full of messy duplicate files. That's why I recommended that the jav-it can have a roll-back function to delete whatever generated previously before running it again so that such issues can be avoided.
an incomplete file with .bc! file extension gets downloaded with the files
extra files re-generated due to incomplete files with .bc! extension previously were detected as movie files
titles become missing in random nfo files
As for the tag called "JAV" it is important to some users because they didn't sort their files correctly in the first place. Only JAV movies require jav-it to be scraped hence it doesn't make sense for them to include their other collection in the same folder. The default shouldn't include this tag. It looks weird having to organise in movie type yet another tag for the same movie type. It isn't important just that OCD people will get annoyed by it.
