Gstr 1 - b2c invoices wrongly uploaded in b2b

Hi all
        
     I have filed GSTR1 from July 2017 to March 2018 . But supply to one party ( actually the party is unregistered under GST ) have wrongly shown under B2B invoices with another Partys GST number.

How to resolve this issue. Required to show the same in B2C & to remove the wrongly posted invoices with another Partys GST no from gstr 1.
