Discount Element Problem/Browser Cache

Currently at my checkout page on webflow ecommerce ,I have a discount element which users can see only when they are logged in.When I firstly logged in , I entered a promocode and it automaticly calculates the discount.Then when I log out or refresh the site the calculation stays always there.So my browser remebers it.I would like to have once I refreshed/logged out the page the calculated discount amount shouldn’t be there anymore.Also the datas as “Name”,“Email” an user should input for checkout stays there still after refreshing or logging out.
