Charges in f&o segment

In my intraday trade for Banknifty Dec 34700 PE on 24Dec , 2021, I had made a profit of approx Rs 422 but my net obligation id showing in debit.?Why is it so?

Does attempting multiple trades at different proces in same PE will amount to as many number of brokerage per trade as number of trades attempted even if the trade was in same contract and is this perhaps the reason I see a debit of approx Rs 62 even after a day closing profit of approx Rs 422?

How many orders were executed? Approx 20?

Brokerage is charged per executed order.
The strike doesn’t matter.
