The shows is like this
TV Shows > Kingdom > Season 1 > Kingdom.2019.S01E01.Episode.1.1080p.NF.WEB-DL.DD5.1.x264-MZABI > Kingdom.2019.S01E01.Episode.1.1080p.NF.WEB-DL.DD5.1.x264-MZABI.mkv
So they no longer look like this? If they are indeed correctly named, chances are you will have to perform the Plex Dance, search the forum for the procedure.
When there are multiple version (years) of a TV series, its always best to include the year in the top folder, so there’s a better chance of a match. It also looks like you have a subfolder for the episode itself. Plex probably won’t work that way. Proper naming would be something like this
Kingdom (2019)
… Season 01
… … Kingdom (2019) S01E01.mkv
It’s usually best to use the title the way the TVDB displays it. I noticed this series just has “Kingdom” for the 2019 series. So, it might work with just the title
OK, so you didn’t rename your files to Plex’s recommended format. There are so many things in your format that will throw out the scanner; full stops rather than spaces, year not in parenthesis, random tracker/group/quality information at the end.
I don’t know what to tell you, follow the guidelines laid out by Plex and you will have far less headaches like this.
