Hello,
Thank you for choosing our theme and contacting us.
Taking into consideration that Header Builder has been activated in your Theme settings > Header, you will need to navigate to WoodMart > Header builder. There, you can see the list of all the header created. Chose yours one and change elements as per your needs.
Please find more details here: https://xtemos.com/docs/woodmart/header-builder/woodmart-header-builder/
