Here is the solution

No problem, just ask whenever you have question.

No.
Shipping address is the address where the products must be shipped.
Payment address is the address that is displayed in the invoice and where the invoice must be sent.
So, both address is related to the customer.

I cannot see any issue.
Could you create a screenshot?

Your site is in maintenance mode, so I cannot check it.

Where should your address appear?
Please explain.

Install notepad++ and use utf8 encoding as suggested above.
