I can see that now the language codes are also 3-letter inside of Plex.  
Perform the [Plex Dance](https://forums.plex.tv/t/plex-incorrectly-identifying-tv-episodes/100265/4 "Plex Dance") with the file and see which subtitle track gets selected automatically.

Little tip: when you remux MKVs, uncheck all those ‘tags’ and ‘Global tags’ below the subtitle tracks. I have seen them causing some crazy misbehaviour.
