Lanscape has Shadow Seams

Hello all,

I’ve noticed that the shadows on my landscape are making the harsh shadow seams after my lights bake. My landscape’s static light resolution is set to 4 so that it is able to have shadows projected from some of my smaller environmental pieces, and I noticed that when I turned it back from 4 to 1, the seam disappears, but I then loose my detailed shadows. Does anyone know how to resolve this issue?
