It is a default setting in Word to always display markup in Word when opening
or saving a document that contains markup. The idea is that you shouldn't
inadvertently send a document to someone else without noticing that it
contains comments and edits that you may not want the recipients to see.
You can turn off the setting: Click Tools | Options, Security tab. Clear the
"Make hidden markup visible when opening or saving" option. But note that
this won't prevent recipients from seeing (possible sensitive) edits and
comments.

Hi, Stefan,
I am neither opening nor saving when the reviewer's comments become
visible...

Under what circumstances does it happen, then?

I open the file to look at some reviewer comments. I turn off all
comments except for the reviewer of interest. This includes my own
comments as well as informative comments for the template I'm using.
I then start navigating the document by advancing through out, or
paging up. I don't even have to make any edits. Soon, all the
comments start to show again. When I look at the checkboxes for the
comments I disabled, they are checked again.
