Dummy file.docx
The file dummy file.docx (assuming it all worked correctly) is a specially created, much shorter version of one of the documents. I can't send the originals because they are too long and are not yet for public release. But the headings are in exactly the same form, including the fields. Incidentally, I tried unlinking one of the fields--no good. Unlinking both fixes the problem, of course, but that kind of defeats the purpose.
The file capture2.jpg is the screenshot I wanted to include last time. This is how the headings in one of the real documents are showing at present.
