AWE step with minimum (two) approvals not working as expected

hello Gurus -

I am having a severe time crunch to complete this requirement when i ended up with this issue.

I have a step that has 4 roles as approver's. My requirement is that the transaction should be approved by any two roles. I was able to route the transaction to all the roles. However, the transaction is getting approved as soon as the first role approves it and it does not wait for the approval from one more role.

I have set up the details in the step to "Number of Approvals Needed = 2". What is strange is the AWE monitor shows transaction approved after the two roles approve it but in actual the transaction table is updated with approval status as soon as the first role approves.
