Double taxes amount while importing eway bill data into GSTR1

Whenever I import eway bill data into GSTR1, the GST amounts are getting imported doubled, which I have to edit manually for each and every invoice.

eg. if in eway bill, IGST 0, CGST 14000 SGST 14000, then upon importing to GSTR1, it'll show as

IGST 0 CGST 28000 SGST 28000.

And this happens every time. What can be the reason and solution?

TIA
