AME based requisition approval issue with post-chain edit/approval

We have setup iProcurement requisition approval via AME. There are two sets of approvals:
1) supervisor chain of authority for dollar amount
2) financial analyst approval based on Cost center (no dollar approval authority)

If financial analyst edits requisition and increases req amount (which is still within final supervisor limit) then requisition does not go back for approval. Note that, if financial analyst increases req amount above final supervisor's approval limit, then next supervisor is added on the list.

Has anyone encountered similar scenario and know how to resolve it. Here are steps to reproduce the issue:-
