Annoying "Are you sure you want to do this? Please try again." messages

Whenever I edit a listing I created and click on Save Changes, I get the following screen with the words:
Are you sure you want to do this?
Please try again.

I have to click on the hyperlink “Please try again” which will take me back to my listing page with the changes I had made reset, so I have to make the changes again, click on Save Changes, and this time the changes are saved.

This is happening with all the listings I am editing and its really annoying.

Is this confirmation step built into this theme and how do I get rid of this?
