Hi, im trying to piece together my first extract, a NS ale, so i purchased beersmith to help me out but im not sure if i've got it right. At the moment Beersmith thinks im boiling the hops in all the malt, which i dont want??

I was planning a 10ltr boil in a 15ltr pot. Heres my recipe so far,
3kg ldme
200gm grain steeped (carapils and or carahell, not sure yet)
20gm NS @ 45min
20gm NS @ 15min
20gm NS @ 5min
US-05
23ltrs
So far i end up with 35.4 IBUs. How do i change the boil schedule as far as the malt goes?
Can anyone help, check that im on the right track.
Cheers, Brent.
