OI mismatch : Kite API and NSE's data

Hi All,
I am working on some project where I need to see Change in OI correctly.
1. Yesterday I stored EOD data of some NIFTY options contract (For ex., NIFTY20O2211800PE/11599106)


2. I read yesterday's stored data and was calculating change in OI but Strangely it was not matching with NSE's data
3. Then I Verified The same OI data in NSE's website but it was different..

Please help me with this friends
