widget area header after update enfold

Hello, I update enfold in a web site were there is a widget area to the header (That I create following this post)
https://kriesi.at/support/topic/adding-a-widget-area-to-the-header-6/

Now I add the code to the function.php

add_action( 'ava_before_bottom_main_menu', 'enfold_customization_header_widget_area' );
function enfold_customization_header_widget_area() {
	dynamic_sidebar( 'header' );
}

but there is a problem with the big space between the row of the widget
I try to write css with padding e margin 0, but is the same.

What can i do?

Thanks
