Removing white bar after header

Hello,

I run am trying to remove the white bar that appears immediately after the header but before my page content. Can anyone help with this please and thank you? [ redundant link removed ] is the page I am trying to edit. All pages on my site use Nimble Builder but this is causing a payment conflict when users sign up. Plugin support has asked me to use the default editor and when I do, this issue occurs.

TIA… Ryan
