Kite Zerodha : Buying price calculation if sell is made then buy again

I am using Kite by Zerodha and I am not able to understand the average price calculation, below is the scenario, will appreciate if I can get some help.

I bought 11share on Friday for Rs 734.5. Then on Monday the price fell to 678.35, I booked the loss and sold it. Now as the price increase to 696 I bought 15 shares. So what should be my Buying price(average) ?

As per zerodha it is 724.333. Shouldn’t it be 696.

Thanks

Zerodha has assigned 11 shares as T0 and 4 as T1.
