Won't email form with SSL HTTPS

I cannot get Gravity form to email form content on the HTTPS version of a page. After information is entered and customer clicks submit they get confirmation message and email. However the form does not email the content till 3 days later?

https://www.freedomcyclelasvegas.com/finance-application/

Site does have a SSL certificate.
WP HTTPS plugin installed and "secure post" is checked for the form page.
The form works perfectly if you change the address to "http"
There are several other forms on the site they all work with the https or http at the beginning of the address.

Any ideas what is going on?

Thanks in advance

The customer completing the form gets the confirmation message after they click submit. They also receive an email saying their application has been submitted. However the customer information they enter into the form is not being emailed to the admin address until 3 days later.

David, Odd this is it's only that one form. If I add the https to any other page w a form it sends. I think I'll just rebuild the form completely.
