Landscape BluePrints are not working properly

Following a tutorial on making a landscape and trying to use the Landmass Blueprints. When I get to the point where i create the topography it doesn’t create a smooth triangular shape like in all of the tutorials i’m seeing. I’ve followed the tutorial step by step so I’m curious whats going wrong here. When I create the landmass its either a crater like the one pictured or a giant column.

Any help would be really appreciated. Thanks!
