Rename your show folder to “The Pink Panther (1964)” and also rename all the files in the season folders below to match. You’re more than likely currently matching to “The Pink Panther Show” which indeed uses the order/episodes you mention.
Or, compare what you have to:
https://watch.plex.tv/show/the-pink-panther
And:
https://watch.plex.tv/show/the-pink-panther-show
And then use the appropriate show name and release year.
After taking either of these approaches, you’ll likely need to Plex Dance the entire show.
