Header Transparancy

I've followed the instructions in this post - https://catchthemes.com/support-forum/topic/remove-fixed-header-top-dropdown/ and turned off the Header toggle. However that option drops the page down with the header inserted above. When you use the toggle, the header is nicely imposed over the featured image with some transparency so the image is showing through the header. Is it possible to remove the toggle and retain the header overlap with the image?
