GSTR1 return filling for aug-sept

Dear Sir,


We have  GST Registration,my registration No-27BSLPD1932L1ZL. I have chosen quarterly return file option on GST portal because our turnover is below 1.5 crore. But when we choose September month  on return dash board for filing return for period Aug to Sept 2017,only September months figures are auto catched in GSTR 1 form. August months figures are not display in GSTR 1 form.

So we kindly request you please give information about this query & co operate us.
