Charged words but no proofreading

I copied my text into the correct box within the "Check Your Writing" Tab and pushed the "Start" button. After a quick window that stated it was "checking my text" no proofreading or edits were shown what-so-ever. I tried various different texts that I had and there were no changes. I was deducted words however. What is the problem? Thank you.
