How to remove Mailchimp integration Double opt-in?

I contacted Mailchimp to remove the double opt-in for my forms. They are telling me the double opt-in is happening from some setting on my JotForm forms.  How can I remove the double opt-in?

During the integration setup there is an opt-in option:

You can also edit the existing integration and uncheck that box to remove it.
