DH not rending all Chunky blocks

I decided to load a chunky circle of radius: 8000 blocks. Once i turned on LOD chunks, i could see there was a lot missing. I attached a picture of the world to this post. You can see some of the outer rings of the circle. The missing parts will load in and stay loaded in once i go in them (you can see a small squiggly line connecting one of the parts to the main body near the bottom). Is there a way i can fill these back in without going over each section?
