Some media show "Unknown (SRT External)" and "English (SRT External)" in Plex

So like the title says, some of my media files show both of those options in Plex even though I only have one SRT for that specific media file. Here's an example:

Here's is S10E12 in Plex:

Here's the mediainfo of that file:

So what gives?

Interesting, can you show the XML dump from Plex Web? Also, post the logs after you refreshed this episode?

This is another episode of another show but it basically has the same issue:

Please post the logs after refreshing that particular episode in PlexWeb!

I accidentally deleted the file after watching it earlier, sorry. But I redownloaded it for the sake of recreating the issue. The problem is that as soon as I downloaded it and it was imported in Plex, I don't see the issue anymore. I'm trying to find another episode that has the issue now and I'll get back to you.

Could this be a temporary Plex metadata issue though?

Might be, that's why I was asking for the refresh :)
