When GUI language is set to english and preferred subtitle language to Greek the subtitle language is english
when GUI language is set to Greek and preferred subtitle language to Greek the subtitle language is Greek
I am referring to internal subtitles only, external are working ok
Is that normal behavior?

An internal subtitle in a video file can be set to 'Default' and/or as 'Forced'.
What are they set to in your video file(s)?

Multiple subtitles language and none of them are forced or default. Is that matter when I choose Greek language in GUI then the Greek subtitle from the video file picked up?

in my previous post I wrote the external subs working ok, that's not entirely true. After some tests if there are two or more external subs eg en.srt, el.srt then again Kodi prefers the en.srt if GUI language was set to english
