Membership 2 registration shortcode not working with IE

When users are trying to register via this page (this page is utilizing the short code below) using Internet Explorer its redirecting them back to the registration page.

Registration shortcode being used:
[ms-membership-register-user title="" membership_id="65" hint_first_name="First Name" hint_last_name="Last Name" hint_username="Choose a Username" hint_email="Email Address" hint_password="Password" hint_password2="Confirm Password"]

Upon being redirected to the registration page they are also registered as a user (WordPress user only) but not assigned to the appropriate membership subscription.

I have only been able to re create this issue using Internet Explorer.
