Duplicated Calendars with Exchange when Delgating

When I go to my main calendar that is synced with office 365 business (Exchange).  I right click on the account name with calendar and hit delegation.  Click on show button no user is added, add the user that has delagated the calendar to me and the calendar appears.  Repeat right click to show users that are delegated it shows up blank and if I add the other user again it duplicates the calendar and the calendar cannot be reviewed.  Is there a better way to show another user in the organizations calendar after it has been shared to me via the OWA?  Also, how do I remove the duplicate calendars?
