REGARDING GSTR-9 LIABILITY URGENT

Dear sir
there is a difference between gstr-2a itc and gstr-3b itc in table 8 of gstr-9.
gstr-2a auto-populated itc is lesser than claimed itc in gstr-3b.
reason is that 2 of my suppliers didnt file their gstr-1 yet however they have filed 3b for that particular period.
but i have proper invoices.
thats why gstr 9 table 8 showing liability.
what should i do?
should i pay liability through drc-03 or wait for case notice to show proper invoices to officers (u/s 16 of cgst act rule 36 & 37) that its not my fault that they didnt file gstr-1.

please help i have not file gstr 9 yet.
