Hello,
First of all make sure that you are using the current header, Woodmart theme provides the option to create different headers for different pages:

You can check the custom header for a separate page and edit it.

If the issue remains, please deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Otherwise, if the issue still exists then keep the 3rd party plugins deactivated and share the WP admin login details of your site so I will check and let me know I will check and give you a possible solution.
Best Regards.
