Playing mkv with bad subtitles

When I try to play back an mkv I’ve made from my dvd (makemkv), the subtitles don’t display for the proper time but just flash by - is this a known bug?

Will it be fixed?

What version of makemkv?

It looks like it was a known bug at their end that was fixed as of v1.6.12.

Ah, it was 1.6 - off to try the newer one.

Thanks.
