Approval Workflow -- completed tasks not showing for Approver.

Approval Workflow -- completed tasks not showing for Approver.

When using the Approval Workflow, as the Approver, i can see the Pending Tasks, and can Approve or Reject them.  But then I cannot see them in the Completed Tasks.  The user that submitted the task is able to see them in the Completed Tasks, however.  I thought when I first tested this, i could see them as the Approver, but I have no idea what changed.  Anyone have any ideas what could cause this?
Thanks!
