Order Slicing issue

I am facing issue in order slicing. Order is slicing in only two parts. If I tried to buy large quantity then order is slicing only in two parts. Suppose I tried to buy 3000 bank nifty quantity i.e.250 lots. then order should slice in 4 parts. But when I place order only two slices are showing. This is happening since morning. Please help.

Can you share a screenshot of the problem you are facing ?
