Hello,
I have visited your website. The sticky header inherits from the main header and its modules. If you want to display a custom sticky header then you need to select it as sticky from Woodmart >> Header Builder >> Edit Header.

You also need to edit the header settings from the left top and disable the sticky header clone to make your selected header a sticky header.
