After the contact form is filled out and submitted, the filled-in form appear on the screen (as opposed to a message like "Thank you for your submission"). It disappears when you refresh the page so I guess other readers wouldn't see the message, but the person submitting the contact form wouldn't necessarily know this and could think their message just got published.
I've read the support page on contact forms, including watching the video, and checked out the other questions at the bottom of that page, but I'm not finding this issue addressed anywhere.
Thank you in advance. I am a wordpress.com user ([email redacted]).
The blog I need help with is greyhound2.wordpress.com.
