PCG Ground / Ditch BP help (Electric dreams env)

Hello! I’m trying to use Electric dreams env PCG blueprints, and I’ve ran into a problem. When I use the Ground BP it automatically attaches to my FIRST Ditch BP. I’m wondering how to get it so I can attach it to a different Ditch BP? Also how to get the ground BP to work independently from the Ditch BP so I don’t need the Ditch. Thanks guys, I hope I laid that out so its understandable, I’m newer to Unreal.
