Updating contacts in Contacts Groups

[whereisbro]

Hello.

This is the scenario: address book with a lot of adresses and a lot of contacts groups.

If we change an email address of a contact who is also part of a contact group, the change is right in the address book, but does not have any effect in the contact group (or contact groups) where the contact is.

Can anybody please help me?

P.S.: sorry for my poor english...
