I cant get plex to recognize a TV show added to my library

Hey it looks like you named them well, but getting them to appear
takes having your agents functioning correctly before you add them.
If you make changes to agents after, it can go haywire.

Luckily the trick to getting Plex to forget it ever saw those videos
so you can attempt adding them again,
you will want to Plex Dance the entire series folder.

So now you know how to get back to square one. Let’s get the agents
well understood. Each TV Library you make can have it’s own agent.
Settings - Libraries - Edit - Advanced takes you to the page where you
can see the Agent assigned to that Library.

In my case I chose TheTVDB as my agent. And on Settings - Agents I need to be sure that I have enabled Local Media Assets in that agent.

That should make it happy. Once the episodes appear, you can edit each one to give the eps titles and whatever other tags you like, posters too.
