Any idea?

Kind regards,

The reason is because the creator of your files was stupid enough to flag those track as disabled.

The only reason why VLC shows the track is because that ignores that flag. That is incorrect behavior and for that reason MPC-HC does not do that.

You can fix your files with the header editor of MkvToolNix.
