Does anyone know how to properly name the following TV Series?

Doctor Who (1978) - S16E01 - The Ribos Operation Part 1.mp4

Doctor Who (1978) - S16E01 - The Ribos Operation Part 2.mp4

Doctor Who (1978) - S16E01 - The Ribos Operation Part 3.mp4

Doctor Who (1978) - S16E01 - The Ribos Operation Part 4.mp4

Doctor Who (1978) - S16E02 - The Pirate Planet (Part 1.mp4

My PMS shows it as Doctor Who Season 16 but there are no episode names in the listing.

Please help me as there’s over 25 seasons of it and I would like to have this for my family members to watch.

Name and organize your files according to this list: https://thetvdb.com/series/doctor-who#seasons
It has a separate episode number for each of your “parts”.

Then make sure to edit the show in Plex and select as Episode Ordering “TheTVDB (Aired)”.

Ensure that your episode titles are not overwritten by nonsensical embedded meta tags in your mp4 files.
Either ensure that your files don’t contain meta tags,
or ensure that they are not given priority by disabling “prefer local meta tags” in the properties of the tv show library.
