Bangalore Electricity Supply Company Limited [BESCOM] — Arrears charge in bill

Hi, I am Jenees from Bangalore living as a tenant. We have seperate bill and for the past 1 year I am making my payments on time as I setup autopay for it. Till last month bill I did not see any arrear amount. In this month bill, I see an arrear amount of ₹265 which I did not know why it came. I would like to get a clarification from @BESCOM regarding the same. I’m attaching the recent bill here.
