Why nonrecoverable tax lines associated to PO doesnt appear in Uninvoiced Receipt Accruals Reports?

We have a requirement from client side where a non-recoverable tax in estimated during PO creation and the later adjusted when the tax engine recalculates it.

This works for Accrue At Receipt Transactions.

However, for Accrue at Period End transactions, even though non-rec tax amount is being posted onto GL and getting auto reversed, those amounts don't show up in the uninvoiced receipt accruals report. FYI - We are running this once Create Uninvoiced Receipt Accruals are trigerred with Parameter as 'Report'.

is there a reason why this happening? or this is a missed config?
