Blu Ray MKV Subtitles Problem with Live Hub

So I have noticed a little problem or bug when playing my anime mkvs.

They are Blu Ray rips and it has english and japanese audio and english subtitles.

But when I am enabling the subtitles,  only some of the subs are being shown. Like only a couple of lines are gonna appear every now and then. And when I played the mkv with VLC and other programs, all the subtitles are being shown, so it has to be the WD TV.

Can anyone please help me with this?

Subtitles are still a weak point with The Hub.
