Hello,
This version uses the multiple headers option to show the home page header over the page content (header overlap option is enabled for the home page header). Watch video tutorial https://youtu.be/BpeXfzNwkOc
So, you need either edit both headers to apply changes for both default header and home page header. Or remove the home page header if you don’t need separate headers for the home page and other pages of the site.
Regards
