Min decrement amount and Response revision setting in auction

Summary:

I am facing an issue in Oracle Fusion Sourcing Auctions and would like to understand whether this is standard functionality or a configuration issue.

In the auction, I have configured a Minimum Decrement Price at the line level and enabled the Response Revision Control setting that requires suppliers to submit a response better than the current best price.

My expectation is that once a best bid exists in the auction, all subsequent supplier responses should be validated against that current best bid and should comply with the configured minimum decrement rule. In other words, suppliers should not be able to submit a response that is equal to or worse than the current best response.
