It may be that you have the "
Show Markup" feature turned off. If you are using MS Word 2010, 2013, or 2016, click on the "
Review" tab. In the section named "
Tracking," there are three drop-down menus—they're to the right of the button named "
Tracked Changes." Click on the top one. Choose
All Markup.
Then, click the
Show Markup menu to make sure all the markup options are checked, including "
Insertions and Deletions."
If you still don't see any changes, please feel free to
contact me.
