Assuming that MacWord resembles WinWord in dealing with cross-references, this isn't necessarily a bug...
When you use Word's cross-reference feature, the cross-referenced paragraph will be enclosed in a bookmark. Later, if you add a paragraph by pressing Enter at the beginning of a bookmarked paragraph, the bookmark expands to include the new paragraph. (You
can see this if you experiment with ordinary, visible, bookmarks; you can choose to display bookmarks in the Word Options dialog box.)
The workaround is to recreate the cross-references immediately after you have noticed the problem. (Alternatively, you can redefine bookmarks, but it's a bit convoluted and, it seems, less predictable in recent versions of Word.)
To avoid the problem in the first place, avoid pressing Enter (or adding text) at the beginning of a bookmarked/cross-referenced paragraph. Instead, do so at the end of the
preceding paragraph instead.
