Discrepancies in GSTR- 2 RETURN

Dear all,

I have generated GSTR-2 summary online. There are 18 Nos. of invoices. Out of these I have been accepted 17 Nos. and modify 01 No. But at GSTR-2 INVOICE DETAILS: POINT 3, 4A- Inward supplies received from registered person incl. reverse charge supplies showing 14 Nos invoices and less amount of purchase as well as less amount of input credit. Kindly comment on the matter so that can I get the right amount of credit.
