AP Invoice Approval issue using AME

We have Oracle EBS R12.1.3. and setting up the the AP Invoice Approval workflow using AME.

we have defined the rule as per below.

Rule 1 : Invoice Amount >= 1000 & < 2000

Action Type : Absolute job level

Action      : Require approvals up to at most level 1.

Rule 2 : Invoice Amount > 2000

Action Type : Absolute job level

Action      : Require approvals up to at most level 2.

Now, my invoice amount is Rs.1500 then it should be approved thru user at level 1  ( as per rule 1 ) but invoice is not approved and gone to user at  level 2   ( as per rule 2 ) .    User at level2 can approved the invoice.

Can anyone guide me that what I am missing ?
