How to change heading style numbering format in MS Word?
I see style numbering is not reflected in numbering setup window. Is this a bug? How to change numbering?
Solution 1:
If you are changing any of the characteristics of a multilevel list (which you probably are, in this case), don't go through the Style->Format->Numbering dialog. Go through the Multilevel list dialog on the Home tab of the Ribbon.
Personally, I still find this entire process exasperating so cannot really offer much more help than that, but you may find the late Shauna Kelly's page on the subject useful
