Strange behavior with Word macro

[Ulodesk]

The Createdate field has started misbehaving. It appears to work fine in a newly created document; I have a keyboard shortcut I have used for many years to insert it and right-align it. At some point recently, however, in older documents it began inserting the document's date of creation, so, it may actually be doing the same with new ones but just looks fine.

I have rerecorded the macro, and also tried using Insert/Field/Createdate; the result is the same. This morning I ran an online Office (365) repair, but to no avail, after two computer reboots to make sure the installation was complete.



Any ideas on how to fix this?
