Amend option is not showing to purchase manager

Hi,
Recently, I have created a workflow for purchase order approval. After activating the workflow, the amend option is not showing to purchase manager but is enable in role permission manager for purchase manager. I am attaching some reference image of workflow. Kindly assist for the same.



In workflow at last, purchase manager has the rights to submit the Purchase Order. Purchase master manager is the only for approval.

Corrected the status and transition rules of the workflow. Please refer to the image:-
