Pop Up margins do not seem to work?

Hi there, I have had a number of issues with the Pop Up! plugin as I have been testing it. as you can see in the screenshot I have added some margins and some 50px padding it does not work on images, videos, forms in the pop up! You can see on the homepage of my site the popup but no margins so not sure if this is another bug here? Also shortcodes from gravity forms create an error as reported in another topic and also the mailchimp embed code does not work as the form send button will not show in the pop-up also. I look forward to an update. Thanks in advance
