Gstr-2a new issue

If a supplier files GSTR-1 return for August 2018, while no record appears in August GSTR-2A of the recipient but return filed by counter party is shown as 'Y', the invoice appears in GSTR-2A of the recipient for September 2018. However, the main screen of GSTR-2A for Seprtember 2018 shows that the supplier had not filed return. The reason is that supplier has not yet filed GSTR-2A for September. Now, after filing September 2018 GSTR-1 for September 2018 by the supplier, what will happen to August 2018 invoice in GSTR-2A of the recipient is not clear.
