UPI mandate only for 1 lot

I have applied for 7 lots of Vishal mart IPO, the lot size was 190 and the price was 78. So in zerodha I have place bid for 1330 shares @ cutoff price. I have received UPI mandate after 30 mins of just 1 lot i.e, 14820 whereas the total amount of 7 lot is 103740. Please help as this is my first time applying for IPO. And also zerodha allows 3 bids, is it useful or should I just place one bid of 7 lots at cutoff price?
