This is usually a symptom of an incorrect note
duration (one that is too long) or maybe an extra
inserted note, which cause all remaining notes
to be shifted slightly to the right, and at the
end of the section the little bit left over causes
a new bar to be started.  You are using bar checks,
which is good, so make sure you have these inserted
frequently, in even every bar if the rhythm is complex,
and in all voices, including skip voices, and look for
errors in the log file.  I would hazard a guess that
your skip notes don't quite match the music length.
Check the upbeats are correct too.
