Dual audio problem

[Carnifex]

Hi, as the title suggests, i have a problem with dual audio. I remember switching languages once before without a problem(menu-audio-audio streams-Japanese), but now, the option is greyed out. I dont remember if i had an older version of BS back then.

The files in question are MKV files, 10bit if that matters. My player version is 2.70, the build1080.
