Gstr-9 of fy17-18 not showing the amendments to invoices made in fy 2018-19

I had short-filed 2 invoices . I made amendments to Nov-17 and Jan-18 invoices in Aug-18 GSTR-1 and paid remaining tax in Aug-18 GSTR-3B.

 When I check my auto-populated GSTR-9 ,  Total tax liability and total tax paid are showing old figures , where is my amended figure ? 

 if I manually edit tax liability to add extra tax , then I have to pay the tax , again ? ( I already paid this shorfiled amount in Aug-18)

please guide anyone .
