I found an instance where the "workaround" also fails. BarCounter absolutely does not like to precede the MMR plugin in a measure. To correct the problem, I added an instance of BarCounter after each measure containing MMR (which worked). Experimenting, I moved the "workaround" back one measure (to avoid the MMR). Problem also went away. I adjusted the previous-posted failing score for illustration.
