Solution for UE-149647

I have been trying to follow courses i purchased online for creating my first environment in Unreal Engine 5. However they use landscape layer blend node and for some reason it does not work. Every time I try to connect a texture the the Layer Blend the texture in the preview and in the editor is pitch black. I tried changing the preview wight to .5 and 1 and neither worked. I looked in the issue tracker and the issue was submitted bu backlogged to Unreal Engine 5.1 witch is unacceptable. Has anyone found a fix for this?

Here is an image of what is happening
