FYI -
PG Music Support responded to me yesterday and says this was a bug that they fixed in the 2016 version (yea!).
However, they also said that they just retested my scenario, and a similar problem now exists in the 2017 version (boo!).
However, they said they have passed along the problem to the developers in anticipation of a patch to the 2017 version (yea!).
