There is a UI issue when 2 contacts share an email
I have 2 contacts with the same email address. Different names, different phone numbers. If I click on one of the contacts, it shows their info correctly. If I then click to the other contact, only some of the info is correct. The phone number is still the one from the previous contact. However, if I click on a completely different contact and then click on the second contact, the information is displayed correctly. It appears that the details pane is not refreshing completely if the email address is the same.
