Edit page - 1 edit is "too many"?

Just trying to edit a simply typo error on a page.
Edited a single letter in a single word, and added a brief description as requested in the box below.
The page would not save but instead gave this message at the top in red:
"Your corrections cannot be processed because they include too many changes to the original page."
Is there anything I could do about this problem?
Thank you.
