AME Approval

Hello

I have a requirements to enable AME approval for Purchase requisition, I have done this request and it's working fine except one scenario i could not be able to achieve.

The scenario is this:

1. When Requisition submitted by user XYZ, it should pass through approval group XYZ-Group. This is working with no problem.

2.  When Requisition submitted by user ABC, it should be approved direct without passing through approval. (Here's  the problem, still passing through approval Group XYZ-Group although rule not applicable )

any idea please

Thank you
