Hi,
I suggest you try to reset Word for Mac, please follow these steps:
Quit all Office applications.
Open Finder and go to ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates, move Normal.dotm to Desktop.
Go to ~/Library/Preferences, locate the files com.microsoft.Word.plist and com.microsoft.Office.plist, move them to the Desktop (Word will rebuild them).
Restart Mac and the application.
