Avatars for People (Contacts) in Outlook for Mac

I'm trying to change the avatar for a contact  stored in my hotmail.com account in Outlook on the Mac.  I right click on the listing on the People (contact) page and check "Edit."  The avatar that appears on the contact card is not the same as the avatar that appears on the People listing page.  No matter how I edit the Avatar in the card listing, it does not change the avatar that is displayed in the listing.  Any so solution for this?
