PayPal Checkout buttons only appear on order confirmation page, not on payment p

-- HikaShop version -- : 6.4.1
-- Joomla version -- : 3.10.2
-- PHP version -- : 7.4.33

Hello,
I am using the latest version of HikaShop with the PayPal Checkout plugin.
I want the PayPal Smart Buttons to appear directly on the payment checkout page. However, they do not load there at all. When the customer is on the payment step, they only see the radio button and the payment description. The actual PayPal buttons only appear later, on the final order confirmation page.
My checkout workflow has the Cart and Payment blocks configured together, but the buttons still refuse to render on the payment page.
Could you please help me figure out how to make the PayPal buttons load directly on the payment step instead of the confirmation page?
Thank you!
