Landscape Clipping Through Spline At Distance?

Hi all, very new Unreal dev here. I’m working with splines to make roads, but I’ve noticed that in multiple locations along my spline, the terrain clips through the spline when viewed from a distance. Since my splines deform the terrain, adjusting the control points ends up adjusting the terrain with it, and I can’t figure out or find out how to keep this from happening.

Is this due to my lack of knowledge in setting up LODs, splines, or something else? Thanks!

Any advice or suggestions would be appreciated!
