Thank you Aki! :) :)

Uncommenting the prefix, and removing the maildir++ virtual.all & virtual.flagged got it working as expected.  I don't think I would have realized that the maildir++ virtual.* is for a different use.

Really appreciate your time and explanation.

Why did you leave the prefix uncommented? Also you already have maildir++ folders virtual.all and virtual.flagged, they are not related to this, and you should remove them.

uncomment the prefix, and you'll see virtual.All and virtual.Flagged folders.
