Table 6a of form gstr1 || gst ||

as i file GSTR 1E i.e., ( Table 6A of FORM GSTR1 ) so the gst portal shows the file return buttom as not active and if i fill boxes with 0 and 1 to just add the invoice so as to file return so gst portal says "You already have Submitted/Filed GSTR1 For Current Return Period"

AND if i go to file gstr 1e for the m/o aug 2017 so it says that the GSTR 1EX is not filed for pervious period 

What to do now ?? 

Valuable suggestions will be appreciated . . . . 

thanks !!
