Hello,
WooCommerce plugin gets the uncached cart details on every page to show the latest cart items by calling the admin Ajax and uses component “wc-ajax=get_refreshed_fragments”. The same for the wishlist.

As you can understand it’s not only our theme issue. If you use cart and wishlist in the header you will have these components. If you want to remove them you may try to remove minicart+ number of items from the header and keep cart/wishlist icons only and disable cart fragmentation using custom code.
