How to modify the existing delivery addresses in the magento2 payment page?

How to change the existing delivery address in the payment page. Magento2 has the option to change the address for only the new delivery address added.

Magento Client View Frontend Web JS Template Client Address.js

isEditable: function () {
return true;
}

The Edit button is displayed for existing delivery addresses. Please find the screen capture.

View existing delivery address data in a pop-up window when you click the Edit an Existing Delivery Address button.

But the new delivery address displays instead of the existing delivery address when you click on the existing delivery address.

How to solve this problem. Thank you in advance.
