trading issues on zerodha

I want to ask queries about trading equities on NSE
i have bought 6share of bhartiairtel at average prize of 371.5 rs per share on 5/06/2020
but in my demat account buying prize is shown 581.5 rs per share
if you want to check it please check on my tradebook on same date
thank you

How can you buy shares at 371 when Airtel was trading in range of 567-590 on that day.

I think there is some kind of confusion.
She might already have some shares in her demat account, and after the 6 new shares , avg price changed to 371.5

But as obvious buying price is 581.5
