Which two series is it?

Some series are represented differently in TMDB than TVDB. Plex uses the numbering system of TMDB **by default** , so if you are expecting it to be the series from TVDB you might have issues.

Do the [Plex Dance](https://forums.plex.tv/t/the-plex-dance/197064) on the files, and if it still doesn’t show up, use the tip Ozsmac posted about forcing Plex to match the folder automatically to the right show using the `{tvdb-TVDB_ID_HERE}` text at the end of the folder name.

Another thing to check is that you are properly targeting the correct folder for the library itself.
