Gst credit in case of new regi. against old reg. cancelled

Dear Members,

I need a guidence against a small metter relating to GST, I have subscribed a service in July month, the Service provider has issued me an invoice but cancelled the registration taken.

The same service provider taken new registration but in August month and provided me new Regi. number.

While preparing Form GSTR-2 I tried adding invoice in missing section with old registration number and new registration number as well but GST system is not allowing me to enter cancelled number.

and on the other side if I enter the same bill with new registration number it is showing processed with error. Error is: "Invoice entered is before the date of Registration" in this case guide me, how do I complete my GSTR 2 taking credit of the Invoice........

Thanks in Advance
