OK, I have it working. I guess this is "user error", but all I wanted was to use a delimiter to show the delimiter Title. I didn't need the description.
But ... in order for the delimiter to show, it MUST contain something in the Description .. even if it is only a blank space. I hope this helps someone else.
I don't think it should be necessary for the description to have something in it just to get the title to show ... but that's how it is currently with version 1.8.
