Trees turning black having text in the center of them depending on how far I get away from them

When I get some distance from the trees in game and also in the editor the trees get that black background with the text. It says something about the skydome that I am using which is the normal unreal starter one. This is the only asset currently doing this. Does anyone know what this is and how I can fix it?

Try turning WPO off in your grass material.
