daily candles giving wrong ohlc

I am hitting this api for symbol IOC.
https://kite.zerodha.com/oms/instruments/historical/415745/day?user_id=KQ6529&oi=1&from=2019-01-01&to=2023-09-30

for a lot of days it gives wrong OHLC values for example below is one candle from API:
array:7 [
0 => "2021-11-30T00:00:00+0530"
1 => 76.35
2 => 77.6
3 => 75.55
4 => 76.3
5 => 27563894
6 => 0
]

but the correct candles is:
open = 79.35
high = 80.6
low = 78.55
close 79.3

its happening for a lot of symbols, this is just one example.
