that sounds strange -- from what you write, it sounds like a problem
with the NoteNames context rather than with what you feed into it...
Can you give a simple example where that happens? Have you tried if
something simple like
\context NoteNames { \repeat unfold 40 c'4 }
can provoke the same problem?
