The customer has added more than 10 cards to their account. But only 10 cards are listed on the hosted pages. Why?

Summary

The customer has added more than 10 cards to their account. But while charging, only 10 cards are listed on the hosted pages. The customer is unable to select some of the cards as they do not show up. 

Expected behaviour 

The expectation is to bring in the initial 10 payment methods (including the primary payment method), so you can inform the customer that it’s optimized for up to 10 payment methods.
