Revocation of cancellation of registration

U can file your pending gst return pending for a period prior to date of cancellation order passed by proper officer

In our case date of cancellation is 15th September. we have filed GSTR 3B upto Aug 2020 and GSTR1 for the quarter Apr to June 2020. After filing of these returns, we have tried to apply revocation of cancellation. But still it is asking us to file pending GST return. what we need to do further? there is no pending GSTR1 to be filed upto the quarter Apr to Jun 2020
