Mail address incorrect in Mail when part of a Group but correct in AB

Question

Is there a way to remove previous addresses that have been received in Mail? One of my frequent contacts shows an incorrectly formatted address when I create a new message. It shows the name and the email address but it does not include the first < of the email addy. I have to edit the address each time. The person is part of a group address and this format comes up whether I'm sending to the group or the individual. It does not choose the address from the individual's AB card. And the server won't accept it without my editing the change.
Actually, I have a problem anytime any individual is also part of a group. I would guess it's a product of the Group Card format. The Group address adds a bracket at the beginning of a string of addresses then closes with a bracket after the last on. > so the first address in the group shows a
< email address but no close >. The last address in each group shows name, email address > but no opening <.
It happens with every first and last person in any group despite the fact that the email addresses are not bracketed in the individual AB cards.
How do I edit these groups so that all addresses appear correctly? The editing changes never cause a permanent change because they're taken from the Group format.
Is there a way to delete the incorrect ones that appear when I'm sending a new message?

Answer 1

I have a group called Circle. It has four members. When I select New Message and type in C, Circle is one of my choices. All names under C are followed by email addresses that appear within angle brackets. This is also true for Circle. There are no names within the brackets, just addresses. The first address opens with an angle bracket followed by the first email address then a comma, and the rest of the member addresses. The last email address ends with a bracket. All addresses are within one blue oval.
Under Preferences/Composing, I have 'Automatically Complete Addresses' selected.
I've also just found further down the list, another choice that just says Circle with no addresses showing. When I select that for a New Message, only the name Circle shows in the blue oval (with no angle brackets). The name Circle doesn't expand to complete the addresses, although I have that selected in Preferences. If I open it and say expand Group, it shows all names and email addresses (each of which is within its own angle brackets and blue oval). That may be the link to the Group I created in the AB. Wonder where the other one came from? Perhaps I created it as an email message and outside of the AB? Might that solve this mystery of incorrect formatting?
