Office 365 Word Headings bug


This is the second report I have written where this bug has occurred. Saving the document then opening it Heading 3 numbering becomes highlighted as shown below:

If I go to define new multi-level list this is what I get:

If I click "Font..." for the heading 3 I get the following popup message "The number must be between 1 and 600" irrelevant of what I change the font to, I then get the message "The number must be between 1 and 1638"....

The template I am working from seems fine.... just at some point after saving this may occur and I cant repair it. After this bug occurs when ever I save the document I get the following message :

Many Thanks


The problem occurs because the font characteristics in the list template have become corrupted.  It can be fixed by running a macro containing the following code:

For Each templ In ActiveDocument.ListTemplates

For Each lev In templ.ListLevels


Next lev

Next templ
