Why is Shop Pay appearing instead of Quad Pay at checkout?

Hello,

My quad pay was set up in my liquid themes but at some point it disappeared at check out. I added the code back into my theme liquid but it is not showing up at check out. When I check my settings “payments” I see that quadpay is “active”. When I run a test I select a product and add it to my cart to proceed with checking out I get shop pay instead of quad pay. Can someone help me rectify this issue? I put in a ticket but the support rep said I should go on this forum because they are not coding “experts”.
