Playing with Pro 1.1.1 noticed the following:
- Create a header in Header builder, using primary menu and make global - save.
- Remove header as global.
- Go to Theme Options > WooCommerce > Navbar Menu = On - save.
- Go back to Headers builder and make global again.
As the Theme Options > WooCommerce > Navbar Menu = On is still on the amount and items, i.e. $0.00 Items is displayed in the header.
Possibly a bug, when a Header is made global or assigned to any page/post it should probably set Theme Options > WooCommerce > Navbar Menu = Off in the background.
