This error only applies for normal user after signed in.
When I created a new user, then signed in. Then Click the "My Account > Address Book",

--Create address 1 : Click "Bill To" and "Ship To" button to make this address as the default billing and shipping,then the "Shipping Address" or "Billing Address" changed.

--Create address 2, click "Bill To" and "Ship To" button to make this address as the default billing and shipping address respectively. Both are not working.



But when login as "Admin",it is oK.



So how can I solve this problem? Can anyone give me some advice?

Thanks very much.
