Reports that filter for primary email address only

Am I doing something wrong?  Ive got a filtered report of contacts that displays the contact's email address but I cant seem to find a way of displaying just their primary email address. The report displays every email address belonging to contacts that fit the filter I've chosen. I can filter out emails that are 'opted out' or 'invalid' okay but I want to exclude all active secondary email addresses too and cant seem to do that.

Any ideas?
