How to restore AfterPay as a payment option at checkout?

Hi there I have uploaded a new theme and lost my afterpay option as payment at checkout.
It is still connected, and I havve uploaded the code so the pricing appears on the product page, but it has gone from the checkout. I can’t find any code anywhere to be able to fix this - is anyone able to help?
Thank you.
My theme is impulse and url is www.walkalloverme.com.au

Complete the steps below to position the Afterpay product page and cart page assets on your store:
