This usually points to issues with file naming/organization or issues with embedded metadata.

  1. How do you have the files named and organized?
    Can you provide a directory listing, screenshot, etc?

    You should follow Plex naming requirements as close as possible. See Plex Docs → Your Media → Naming & Organizing Your TV Show Files.

    If you change naming/organization, Plex Dance the series to remove bad information from the Plex database.

  2. Is the library configured to look at embedded metadata?
    If using the Plex TV Series agent/scanner, edit the library, choose advanced, and scroll to Prefer local metadata.

    I’m not sure if embedded metadata overrides non-standard naming, but you could give it a try.

    Configure the library to look for local metadata then refresh the metadata for the library.

    If it does not help, disable the option, as incorrect local metadata may cause Plex problems with properly recognizing and organizing files.
