Currency bug in Edit customer details page

The CustomerCurrencyCode in the order table is different, but the customercurrencycode in order list(as picture shows in customer edit page) is the same.I think it is a very small bug.

I also checked customer account,it is the same like database.

The pictures I inserted did not display.

It's by design. In admin area all prices (and order totals) are displayed in the primary store currency (USD in your case). And "customer currency" is used mostly for customers (in public store)

I am sorry for not committing problem at a time. Thanks for replying.

What I mean is the money should calculate with exchange rate at least.

Let take the order #8 as example in pictures. The money in database is 2987.56EUR, and in admin area the money is 2897.56 US dollar. So my point is the money in admin area should be 3579.0661 US dollar(=2987.56* exchange rate).

It works fine out of the box.

Your primary store currency is set to USD. And the value in database is also 2987. So it's $2987

What order total does your customer see in public store on the order details page? You can use "impersonate customer" functionality to check it

Thank you!
