Incorrect shadows on quixel mesh


I imported a mesh from quixel into unreal engine 5 and get these weird spike looking shadows at the top of my mesh. It is weird, because the shadow from the tree are correct. I don´t know if this is a UE5 bug or a quixel mesh problem. Also, the shadows from the mesh itself are harder than the shadows from that come from other objects. Anybody got the same problem and maybe an idea on how to correct this?
