The Kickflip app installation adds a new "Metafields" section to the product page. Inside this section, there is a field called "Bundle name" where you can edit the default bundle name appearing on the checkout page. The field is set as "Custom design" by default. If the bundle name is empty (no text), on the checkout page, the default product name will be shown instead.
