Cannot Complete Paint Foliage tutorial

My problem is simple. I’m using UE 4.10.4, and I’m currently trying to follow the tutorial for painting foliage onto meshes. However, at one point, you’re supposed to drag the desired mesh onto a black bar in the Paint tool, and I don’t have it. The tutorial won’t let me continue without following this step, so I’m currently at a standstill. Has anyone else run into this problem?

Heck I can’t even tell what the tutorials are even asking me to do. I feel that they are out of date.
I couldn’t get past the ADD Target Layer part from the Landscape tutorial.
I’m using the 4.13 version.
