Bracket order in kite

Today, I placed bracket order in kite but it didn’t get triggered, when the stock moves to the target. When the stock retraced back, it got triggered and hit my stoploss. Sell price=1002.45, trigger price=1002.50, target and stoploss is 2 rupees. Please, see the screenshot and guide, why this happens?? Date 21 aug and candle at 9:45 a. M.
