AME order number not working

Hello Team,

We are currently implementing i-expenses to an Indian client.   As part of implementation we are using AME for approval hierarchy.  The approval hierarchy is based on the expense report template they choose.   We are in a situation where for few of the expense report templates the order number of the approver generated are getting interchanged.   We have checked the order number in the approval groups and it is very much in sequence.     Kindly point us in case we missed to check and need to change the order number in any other place of AME?

Kindly Help.   We are nearing to the GO LIVE and suddenly this has created a problem.
