Never end a file name with part n. Put some additional character behind it.
Better put the ‘absolute episode number’ into angular brackets and after the second dash.
Doctor Who - s01e01 - [001] An Unearthly Child
Why did you merge all the single episodes into one common file?
Plex uses TheTVDB for tv shows and all the ‘parts’ are single episodes there.

- Look up your show on TheTVDB
- Take the title as it is used on TheTVDB. If there is something in parentheses, take that too. If the title contains invalid characters (depends on your file system), like
§ : % *, simply leave them out. - Check the naming and the folder structure of your show. Name the top folder of the show exactly after the title on TheTVDB. No abbreviations. No additional subfolders. No aliases. Add the (year) in parentheses of when episode 1 of season 1 of this show was aired.
- Name the episode files according to the above linked naming guide. Use the same title as for the top folder.
Show's Title (year) - s01e01 - additional info.ext(’- additional info’ can be left out) - After you corrected the naming and folder structure, perform the Plex Dance with all files for this show.
