Installment plan slice not being cleared correctly after upgrade

Hi Experts,

Since the upgrade we are facing issue on some Installment plans, whose last slice is getting cleared instead of first slice. I have checked the Clearing rules and for IP they are correctly defined i.e. grouping on document and sort on 024 - Due date with deferral ascending.

What is strange is if I reverse this payment for an IP whose last slice was cleared and make a payment again then the first slice is cleared instead.

Has someone cross across this kind of issue and know SAP note which can fix this issue.

Thanks!
