I have a multi-step approval Workflow using state machines where at each step the approver can approve or decline and provide comments.  Comments are tracked in a variable in the task form that then populate a list (and subsequent task emails).  The comments and approval/decline dates from each approver are writing to the list except for the 4th and final approver the the BU Finance Leader. Comments for both approve and decline make it to a notification email sent by Nintex, but the comments nor the date for declines make it to the SharePoint List where as the approval comments and approval dates do make it to the Sharepoint list.  The 4th approver appears to be set up the same as the others, but maybe I'm missing something!
