Track changes displaying large sections of undeleted text

I’ve run into this issue myself when working with tracked changes in Word, and I know how confusing it can look for clients. What usually causes this is the way Word is set to display revisions. By default, deletions sometimes show up in balloons on the right-hand side instead of being struck through in the text.

Here’s what worked for me:

Go to the Review tab.

Open the small arrow under Tracking → Track Changes Options (or "Show Markup" depending on your version).

In the Balloons section, change it from Show revisions in balloons to Show all revisions inline.

Now deletions should appear directly in the text with a strikethrough, which makes them much easier to read.

After that, your client will see the actual text that was deleted rather than long balloons taking up space on the side.
