I have a template that uses a custom TOC, custom headers/footers, custom cover pages, custom AutoText that's used for Building Block Gallery content controls, etc. All these elements are saved as building blocks in the template file itself, not in Building Blocks. However, after I, and also other users, interact with any of these elements either in the template itself or in a Word document generated from it, we now receive the following warning message when we close Word:
This issue seems to be linked especially to selection of a different option in Building Block Gallery content controls. Even just looking at, but not changing, a control's properties from the Developer tab is enough to cause this warning to appear.
We've used the same template for several years now and never received this warning message until recently. I've double-checked all the custom building blocks in the Building Blocks Organizer dialog box, and they're all definitely saved in the template file itself. Has something changed in the way that Word handles building blocks, AutoText, and/or Building Block Gallery content controls? How do I need to update my template to prevent this warning message from appearing?

* EDIT BY MODERATOR (CHARLES KENYON) TO ADD INFORMATION ABOUT SCOPE OF PROBLEM 26 DEC 2019
This is a lengthy thread. To summarize:
This warning will appear, without any changes to the Building Blocks.dotx file, whenever the user accesses a building block contained in that file or uses the Quick Parts menu. An analysis by MVP Greg Maxey shows that these actions load the file and when it is loaded, even though not changed, its saved status is changed to unsaved. That is what triggers the warning.
This applies to Windows versions 1908-1912 of Word 2016-2019/365. It does not happen with Word 2010/2013.

It appears this is being fixed. Release 2001 (Insider Monthly) does not have the problem.
