You do not have "write" access to the "Review" task so you cannot modify it. Make sure your User-Group/Role matches what is listed before clicking the "No Decision" link. The Group/Role you should be is listed to the left of the link. Your current Group/Role is Engineering/Approver. So you have to fix "write" access first.
