Can't load subtitles for some movies

Every single movie that has internal subtitle track has will not play any external subtitle.
I will start movie with external srt subtitle. It will load internal one. I’ll pause movie, choose a different subtitles and resume movie. The subtitles will be disabled in OpenPHT, I need to go to “Audio and subtitle settings” enable subtitle option, resume playback. The movie will play without any subtitle track. From now on I can choose any external subtitle even the internal one will not work any more until I stop movie, choose a track and it will force load internal one again.
From this place repeat the whole procedure again.
This behaviour occurring in OpenPHT on Win10 and MacOS X Yosemite and Rasplex 1.0

This is a known behaviour inherited from old PHT, which has not yet been atttended to.
So it occurs in all existing PHT and OpenPHT variants on all platforms.
Hopefully we can fix this for RasPlex and OpenPHT in some future release.

I’ll post a reminder of this to the RasPlex coders. (Also responsible for OpenPHT coding.)

Lovely @dlanor thanks for reponse.

Bumping this: https://github.com/RasPlex/OpenPHT/issues/15
For my parents who need subs this is pretty much big issue. Please take a look into in asap.
Much appreciated.
