VAT Tax code not defaulting as setup in oracle receivables

I have setup a new VAT tax code that will be used on both invoices and credit memo.

When I create an invoice, the VAT tax code populates correctly based on the configured Tax Determining factors and Tax condition sets in EBTax.

However, when I create a credit memo, it shows all configured tax codes irrespective of the value entered in "Tax classification code" column (which is setup in the tax condition sets).
