Pleased to see your reply Mohamed
expected flow:
1. user checkout by paypal, no additional information are needed to be entered.
2. an Order created in admin panel with Firstname, Lastname, Email, Address etc from client's paypal
problem:
i use HikaShop Paypal payment plugin
since my site uses paypal to checkout, Firstname, Lastname, Email and Address etc can be retrieved from paypal when a client finished the payment.
in this case, it is meaningless for a client to input his/her information in the checkout form (in the the site)
in the admin panel, it suppose to record down all the information from paypal in the Order view.
They did recorded in History field but not in Customer, Billing Address and shipping Address (see attachment blank_record.jpg)
