TV Show matching - Plex includes "Series" and then cannot match

Mods: I may have the wrong tag here (sorry)

Hi

Recently I have been renaming all my TV shows using Filebot (it’s a lockdown thing) and, whilst most shows survived the name changes, some did not.

So, for the first time in a while I have has a bunch of shows to match, but all used the {plex} binding in Filebot.

Question: Why does Plex sometimes (but not always) include a season in the name when trying to match thereby ensuring no match?

Here is an example:

Here is the associated unmatched poster showing all 10 seasons:

[edit: removed 2nd question to it’s own post]

Are these mp4 files? They might have an embedded title causing this.

Hi,

Yes, I think that’s it - there was tag “show” with “Dad’s Army: Series 9” (for the season 9 episodes). All the other seasons were blank.

…but, I am still confused because I had “local media Assets” 4th and last on my list. Surely it should have been ignored?
