Paragraph marks appear in deleted text in Track Changes

In the middle of editing a Word document with Track Changes on, paragraph and indent symbols began appearing in the deleted text. Paragraph symbols were off (I never use them) in the body of the text. I have tried all the obvious things in Word, have updated my Mac OS and uninstalled then reinstalled Office. At the time, I was running an old version of Word. I now have 16.57.

The only thing I did differently from normal in my use of Word was to use the ^ symbol. I got it both by (command i) and (shift 6). I sometimes accidentally typed another symbol eg ' alongside it.

I would very much appreciate help with this.
