Hello,
I ran into the same problem.
As I'm relatively new to ffmpeg and all that media conversion stuff, I
used ffmpeg to copy from a BluRay .m2ts to .mkv (instead of using mkvmerge
on the .mpls file).
The result is a file with the problem described above.
Also I noticed lots of metadata gets lost, i.e. language of the subtitles.
I've uploaded a sample here:

The cmdline to build this was a simple -codec copy as far as I remember.
