No phone/e-mail set to Primary upon contact update

To replicate the issue (for the email in the example): 1. import a contact lacking email using csv (Contacts>Import Contacts): First Name,Last Name Test,Subject 2. Note the Contact ID of the newly created contact. 3. Update the contact using csv (Contact>Import contacts, For duplicate contacts:Update): Contact ID,Email <insert Contact ID of Test Subject>, test@somewhere.com 4. Check in contact reports that the updated email for Test Subject is not shown. In the contact view, the imported Home Email is displayed, but the caption is not in bold, indicating that it is not the Primary email. When the email address is clicked and saved with the default Primary option selected, it then becomes Primary and is correctly displayed in reports and contact search.
