Hello,
Please check which header you edit and which header is used for this page. There is the option to set different headers for different pages. Find our documentation tutorial about this here: https://xtemos.com/docs/woodmart/header-builder/set-different-header-specific-page/
If you edit the proper header and the problem persists, provide your site admin access (insert the site credentials into the Private content block under the message area) and confirm the permission for plugins deactivation, switching to the parent or default theme. This testing may take up to 15 minutes. You would better make the full backup of your site.
Best Regards
