Why is my 'finish purchase' button directing to the wrong checkout in Ride theme?

i’ve added a checkout system to my store, but it only works with one of the cart buttons, the one that says “go to cart” is actually sending me to my actual checkout as it’s expected to be, but the “finish purchase” button is sending me to the old (default) checkout that i don’t want to use, these buttons im talking about show’s up in the pop-up of the add to cart button in the Ride theme, does anyone knows if i can remove the “finish purchase” button or change its destination, because i cant modify or set up these buttons at the theme customization

Can you share store link so we can have a look.
