I have all my options set to English. Thanks for getting back to us. I should also point out that I’m running my Plex Media Server off Windows 10. I am using Roku devices. I’ve checked with multiple users. We all see “cesky” for subtitles on new episodes that have been added.
Also, to make matters more confusing. I am not sure if this is related. On a new movie, the subtitle options that appeared, were for various movies. None were for the movie that we were watching. This may be unrelated. I’ve just never seen that happen on my server before.
The metadata team, at last report, has reached out to Opensubtites folks to figure out what is wrong. Everyone is pretty convinced it’s an API failure on their side.
Following his advice is the best short-term workaround.
