Hello,
Navigate to WoodMart > Header builder > edit default header (highlighted star icon), or you can go through the admin bar directly https://prnt.sc/Ct9ehRDvvDV9
Switch to the mobile Header > Hover on the Logo element, click on the Pencil icon to edit it https://prnt.sc/TQpL8DqtyVSi to change the Logo.
If the issue remains, maybe you are using the custom header on your site, The Woodmart theme provides the option to create different headers for different pages: https://xtemos.com/docs-topic/how-to-set-different-header-for-specific-page/
You can check the custom header for a separate page and change it with the default header or change the logo: https://xtemos.com/docs-topic/options-for-pages/
Best Regards,
