When you import new records into Sugar and you include an Email Address field, when the record is created the email address is not marked as a primary email address.
I just tested this on a clean 18.104.22.168 instance. I had in import file that contained First Name, Last Name and email addresses. I imported the data into the Contacts module. After importing the data, if you go look at any of the Contacts their email address is not flagged as a primary email address.
Anything in Sugar or other third-party add-ons and integrations that rely on this may not be able to find or use records that come into Sugar via import. According do some of the docs, they should be marked as the primary: http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.5/Migration/Importing_Records/Importin…
Can anyone else replicate this? Is this a bug?
