IO in sensibul nse option chain differ

When I compare banknifty OI data of sensibul and nse option chain OI they do not match. Can anyone explain the reasons for the difference?

The OI on the NSE website is shown in terms of lots, while on Sensibull, it’ll be in terms of quantity (Lots * Lot Size).

On the NSE website, for instance, OI for BN 20th May 32200 CE is 6413 (this is lots), while on Sensibull it is displayed as 160,325 this is the quantity (6413 * 25).


Thank u so much sir.
