When I select a folder in my Outlook Sent Items and look at the To Field, it now shows emails that are identified as both To and CC email addresses for the same email.  It never showed CC addresses before, only the To line on that specific email.  I only want it to show the email addresses that I sent in the To Field.  How do I get my To Field to only show email addresses that are in the To line, not the CC line also?   

Example:  I send an email To: Joe Smith and CC: Mary Jane, previously, the Sent Item Folder would only display Joe Smith under the To Field.  But now, it displays the To Field as Joe Smith, Mary Jane together as if I had selected the To Field for both, not To one and CC the other.
