Charles,
Thanks. FYI, I did some experiments, and they were consistent with your last post.

Word's use of templates is very complicated, and Microsoft doesn't seem to document the complexities. At least, I haven't seen any Microsoft documentation, except for very simple use-cases.

This is not uncommon though for Microsoft's software. They seem to rely on users figuring-out the details for how things work, and writing articles and forum-posts to explain these details.

Word software-developers at Microsoft must have to keep all of this knowledge in their head, as they also have to deal with this lack of documentation. In my experience, most programmers hate writing prose, including documentation. It's no wonder then that Word is buggy.
