Sometimes subtitles from a different language are mixed with the selected one.
Tonight I was watching the movie Race when I noticed suddenly some Dutch subtitles appeared before the English subtitles. It was to quick to tell if it was the correct subtitles but this seems like a bug. After one or two sentences it disappears. Then after a while it comes back again. I have Plex on NVIDIA SHIELD TV, running plex server 1.7.4. I'm on the latest version of the client for Android TV.
