how do i raise a porch to flash with a stair of 3-treads

[Seth Love]

I'm drawing a story building. On the ground floor, I've created about 3-treads stairs to my porch but when i look at it in elevation, i can see my stairs hanging up on top of the porch instead of being in-line with it or below it.

pls can somebody help me?

Exterior stairs are drawn from higher to lower while holding the alt key

interior stairs are drawn from lower to higher

you could also try the "click stairs" tool
