Amending B2C to B2B

I have amended B2C invoices from April 21 to B2B in month of may 21, as the party GSTIN was locked,

but now the GSTR 3B has auto populated my payable tax of both the B2B invoices of April 21 along with my payable of may 21.

So do I  have to pay the tax again for these invoices , as I have already paid the same in April 21.
