Getting Double Postings to Database

Hi There!
I’m using Contact Form DB along with Contact Form 7 email verification and getting double entries to my database.

The email verification is for the double opt in – it holds the form that was submitted until the user clicks a link in their email and then it submits the form data through to our email. I suspect (based on time stamps) what is happening is that the Contact Form DB is posting it both times – when it’s initially submitted and then once it clears the verification. Is there a way to install or edit the code so that it only captures one of these points or even de-dupes itself on the database side?

Thanks so much! 🙂
