Problem with blackpetrucci

[Kees van den Doel]

In black notation minim looks like modern 1/4 note and semiminim looks like modern 1/8 note.

It is not correct though, semiminim and shorter notes are one flag short, so Minim and Semiminim look identical. See example.

Unless I'm missing something this is a bug, is there a workaround?

Thanks,

Kees
