When going to the Team Status page, a team member appears twice as seen in the first two lines of the image below. There is only one user with this display name in the subscription, how did this happen and can it be fixed?
The user was removed and then re-added at a later date to the subscription with the same username and display name. To repair this issue the tasks previously owned by the user were reassigned to the user using their new account. This caused the duplicate listing to disappear and all tasks to appear under a single listing of the user.
