When you are voting Reject on an 'Iterative Approve w Changes and Reject' or 'Iterative Reject' Review task, the Step Checklist items should not be required. The reviewer may have not completed all the steps as the review is not yet complete and will need to be reviewed again.
For example, the reviewer found an error in the email content they are reviewing, so they cannot tick the box that the email is ready to send.
When you are rejecting an iterative review, the reviewer will be reviewing again where they can confirm all the steps have been taken. The step checklist items should be required for the Approve vote only.
