This could be caused due to a user reviewing work item submitted by him/her.



UPDATED: June 2, 2017
For the same user, it is not possible review submitted work items submitted by him/her own. The idea of workflow is that if one user submits a work item, some other user has to review it and decide whether it can go forward as it is, or maybe some alterations are necessary.

Using a different user, should resolve the issue and work item should be reviewed successfully.
