How to fix the 404 error when resending gift cards?

[UrgeSupport]

Hello,

I'm creating a shop for a client and have noticed an error while purchasing gift cards. After purchasing a card and then clicking on the "Resend gift cards" button -- I'm directed to a 404 page as shown below. I can't seem to correct this, and speaking with Shopify support has been fruitless. I would like to fix the button or at least hide it in CSS, but I can't figure out how. I don't have access to checkout.liquid

Any and all ideas would be great.

Thank you!
