Hello,
Thank you for choosing our theme for your project?
Do you have problem with the header on the home page only or with all pages? If you have the issue on the home page only then go to Theme Options > Header builder > Click the Multiple templates link and remove the home page header. If you use the cache plugin or server cache keep in mind that you need to clear the cache to apply changes on the frontend.
Watch video tutorial for the Multiple headers https://youtu.be/BpeXfzNwkOc to find more information about this option.
If you have issues with editing header styles for all the pages then provide us with WP Dashboard access to your site. We’ll check the problem.
Regards
