Gstr 3b - Reverse charge liability

Dear Frnds,

I Submiitted GSTR 3B for the month of Oct 17 (not filed). Since i submitted the return after due date. I need to pay Late fees. So, i deposited Rs.1,000 into Electronic Liability ledger to pay late fees of Rs.180 and Reverse charge liability of Rs.180. Whereas, Late fees showing as "paid" in Cash but the Rever charge liability of Rs.180 is still showing as "Balance liability" under the "Payment of tax" in GSTR 3B.

Please tell me how to clear the liability of Reverse charge using Electronic Cash ledger balance.
