Hmm... But why does this problem happen only for ts files, not mkv files.I've found out the trick: if you set the prefered subtitles language to Japanese (ja) then these subtitles are automatically enabled.
Any other language or a blank setting and you have to manually enable them.
Thank you. I uploaded.Works for me too, but for your convenience I have uploaded it here:
