Hi,

Here is the necessary CSS:

.header-sticky #sp-header, .sticky-header #sp-header, #sp-header.header-sticky, #sp-header {
    background: transparent !important;}
.com-sppagebuilder #sp-main-body {
    margin: -60px;
}

But you need to remove the following two lines first, to get my code as working solution: https://cleanshot.com/share/x8PnvnGm

I think you have added that in your template's custom CSS field. Since it has !important already so it doesn't overrided by my code.

Let me know if you need further help.

Best regards.
