WooCommerce double header only after login as admin


I have really strange behavior after I’m logged as admin (of course I did everything as said in: https://roots.io/using-woocommerce-with-sage/), WooCommerce is adding another content after ‘main’ class.

Other roles and logged customers are working fine, only admin double head content.

When I’m trying to change templates files in my sage theme folder, page isn’t responding. It’s like after logging as admin WooCommerce use it’s default template and not the one that’s overrided in theme folder.
