Hi,

Try to remove all previous header related custom code and add the following CSS code snippet to the Global Custom CSS area.

.whb-header.whb-sticky-real.whb-sticky-prepared {
	padding-top: 140px !important;	
}

@media only screen and (max-width: 1024px) {

.whb-header.whb-sticky-real.whb-sticky-prepared {
	padding-top: 100px !important;
}
}

Regards
