Plex not grabbing local poster assets when using NFO series agent

Server Version#: 1.43.2.10687
Player Version#: 4.159.0

Issue

Plex isn’t picking up a new season poster (Season30.png) for a show. I am using a custom agent that utilizes the Plex NFO Series agent.

When I click “Refresh Metadata” on the TV Show in question, it very briefly shows activity, but doesn’t actually seem to refresh all of the seasons (including Season 30, which isn’t picking up the local poster file).

For my use case, I have very few TV Shows with .nfo files. For the majority, I am expecting Plex to fallback to the Plex Series agent for matching (and still pull local posters for the show/seasons). This scenario applies to my current issue - the TV Show does not have any .nfo files (but does have local posters).

- Agent is configured correctly, and is selected for my library

- Not processing the seasons at all?

- Not showing the local Season30.png poster in the UI

Please let me know if I need to provide any additional information, or if I’m simply configuring anything wrong.

Thank you in advance for the help!
