Your cart shows "Codes applied: Current Promotion", indicating a discount has been applied automatically without requiring the buyer to enter a Discount Code.
If you create a discount in Seller Admin without any Discount Code (i.e., if the Discount Code field is left blank in the discount's settings), then the discount gets applied automatically to every order that meets the Min. Item Total/Qty. threshold(s) you set for that discount.
To fix this, you can go to Seller Admin > Cart Discounts, select the discount from the menu there and click Load to view its settings, then add something in the Discount Code field and click Submit to save changes. Then that discount cannot be applied unless a buyer knows that exact code and enters it in their cart.
