Subtitles set to "Always Play" not playing in some shows

[Hvardrino]

I set the subtitles to Always play in my profile settings but still there are some shows where i have to manually select them everytime.
Even in some shows i still have to select them if there is other subtitles language

If a sub track is marked as "default" (as with your Big Bang screenshot), it will override language preferences in the client. For your One Piece example, do you have transcoding disabled? ASS subs often require they be burned in.

Which player are you using? Integrated, web, or external?
