Does this issue occur with all Word documents?
I suggest you click on Tools > AutoCorrect Options, ensure the Automatic bulleted lists and Automatic numbered lists checkboxes are selected.
Please also make sure Office for Mac is updated to the latest.
If the steps do not work, you may recreate the Normal.dotm for Word to have a look.
- Quit all Office applications.
- Open Finder and go to
~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates
. (Shift+Command+g). - Find the Normal.dotm and move it to Desktop. (Word will rebuild it).
- Launch Word to check whether you can create a document, and then check this issue.
