Expense report approval issue when reassigned to another user.

Summary:

When expense report for inactive user is delegated to another user, user is able to submit expense report on behalf of this inactive user as expected. As per our rule, the expense will route to submitter's approval (Approval level = 1) and will get approved once the manager approves.

However, when the expense report is reassigned from Submitter's manager's queue to another user, then, system keeps routing this expense report all the way upto the top of the hiearchy (upto CEO level) instead of stopping at the reassigned user itself.

Can you please suggest a solution such that if the expense report has been reassinged, it should stop at the reassigned user only and not keep routing all the way upto the CEO level.
