MailChimp MailMuch Plugin Padding issue

Hello,

I installed this plug in https://wordpress.org/plugins/mailchimp-forms-by-mailmunch/
on my Divi themed wordpress website and it’s affected the top padding across my entire site. It seems to be top-padding: 145px rather than top-padding 90px. I’ve deactivated and deleted the plug in but the padding issue remains. I’ve tried css to correct the problem, but this in turn has affected the full page header on my home page and how it resizes for mobile/tablet/different sized monitors.

Is anyone able to tell me how I could correct the issue?

My site isn’t live so I haven’t included a URL at this point…

Thanks in advance,

Dannielle
