If you create reviews for the wrong stage (usually by listing the wrong stage in the Review Scheduling Workbook) you'll want to fix the problem. Because Submissions and Evaluations are automatically created when Reviews are created, it's generally easiest to delete the wrong reviews and create the correct ones. The process for doing this depends on whether or not there have been submissions or evaluations submitted by the team and the grading coaches.
If teams have submitted Submissions and/or coaches have submitted Evaluations, you MUST save the submitted files before you delete the Submission and Evaluation, respectively. Otherwise, you will need to ask the teams and/or coaches to resubmit. And you don't want to do that!
