Hello,

Thank you very much for choosing our theme and for contacting us.

This option makes the header default it would be shown on all the pages, provided no other header has been set in the page settings: https://xtemos.com/docs/woodmart/header-builder/set-different-header-specific-page/

If you have set the default header and page settings are configured to none or the same and it does not appear, please clear the cache.

Best Regards
