Can you please provide a screenshot of the add folder section of the library?
Edit: I am not seeing anything major in the logs. I didnt see the server startup logs anywhere in the zip you provided. So restarting it may not be a bad idea. I see there are 2 similar shows, might want to pull both out and Plex dance them.
Suggestion. Remove the 2 similar shows from your library, re-scan the library, empty trash, clean bundles, reboot the server. Wait 5 minutes, add shows back to library, scan library. Wait for scan to finish and wait an extra 5 minutes. Then post the new logs.
Edit of the Edit: Make sure that the prefer local metadata is disabled.
