    This issue is only for weekly Banknifty contract. We are already looking to this. Will update here, once rectified.

    @rakeshr I am facing the same issue. This issue has been particularly arising since the naming convention of trading symbols of weekly BANKNIFTY options changed. Before it used to be BANKNIFTY03JAN27500CE, and now it is BANKNIFTY03JAN1927500CE (the year 19 was absent).
