Firstly I want to say I'm using Plex on a Samsung UE55F6510SS. The shows that I watch have embedded subs in English and I have external subs in Romanian. Now the problem is that whenever I select Romanian in the subs options it displays 2 times like in the picture below, and if I try to deactivate the first one, second one is working for a few minutes and than I have to turn the subs back on and the problems comes again.
