Oracle Fusion Payables Invoice Approval - Minimum two approvers using Job level with Amount

Hi Team

We have a requirement where approvers should be assigned as below:
1. First requestor
2. Based on a Invoice amount & job level remaining approvers
3. Minimum two approvers should be there for each invoice since first one is Requestor itself.

The issue is when requestor is entered who belongs to higher job level and invoice amount is low, then it is only getting assigned to the requestor as that amount is within his job level approval limit.

Could you please suggest how can we instruct system to have minimum two approvers irrespective of amount and requestor. I have attached the rule configured spreadsheet(zip file), kindly refer rules starting with 'US_'
