Subtitles on top of subtitles on top of subtitles topic

Hello

Since last update the subtitles have been acting strange - they hang, then the next ones appear on top, making everything practically unreadable. MXP has been working flawlessly until now. Same file tested with BS Player, worked just fine.
Is this a bug or just my tablet (Odys Aeon, Jellybean 4.1)?
