they are using their own optin monster account

It's just for CoolSculpting and Laser Hair Removal.  The login is info@suddenlyslimmer.com. Password: Suddenly@2020.   

Hello whitney.zelig@gmail.com

the output of the popup looks so weird, I tried it in both medstar acc. and their personal acc. but still the same.

sent email to: info@suddenlyslimmer.com
no thank you page yet because their service page has a different format.

Isaac  any idea why this is weird?

whitney.zelig@gmail.com  - It was because of a custom css defined in one of the stylesheet on the website.

I have added custom css in the popup settings to overlap that css for both popups.
