Why is my landscape still black?

Hey, I just started using UE5.6 and I am having trouble getting the landscape to apply. I was following this tutorial (https://www.youtube.com/watch?v=k-zMkzmduqI&t=1810s) and I got all the way to creating the layer info to paint the landscape, but even after creating the layer info my landscape is still black. In the video, as soon as he created the layer info the texture applied to the landscape, what’s going on?

I get this too. I always have to paint the bottom layer myself. Even changing the weight does nothing for me.
