The VC code was removed and the issue still happens. From my testing it only happens with your theme. I reached out to woocommerce and they also said it was an issue with this theme. If you add an item to the cart and then add a coupon the link no longer works. I added the product called freeze relief kit to the cart. Went to cart to check out. Added coupon code FR1, Then when I go to click the terms and conditions link it no longer works.
