I noticed a whole season of one of my shows didn’t have subtitles on Plex. This is odd because every other season did, so I went to check the actual folders. All of the subtitles were there, and were actually named correctly too. I wasn’t sure why they weren’t showing up in Plex, so I renamed the files from ...en.srt to just ...srt and they showed up. This was even more odd because there weren’t any issues with any other subtitles named that way, so I renamed them back. Plex continued to pick them up so I figured this was a strange transient stale local asset or metadata problem. I hit the “refresh metadata” button and it fixed the entire season, confirming that the names of the files weren’t the issue
