Export of Zero Rated products in GSTR1

dear experts

we have Exported some zero rated goods.

how to show that in GSTR1

if we are showing in table 6A in zero rated column and selecting the option export with payment if tax then portal not accepting that,
if we select without payment of tax then it allows to proceed but we don't want to select that since the product itself is zero rated.

kindly suggest where to show that in GSTR1
