Not rendering LODs further than a set distance

I have generated all chunks around me in a 4096x4096 circle, and can confirm that they are loaded and the DH LODs have been created, but they do not render for some reason, even with the DH render distance set to 512. They load when I get closer to them, but then unload when I return to my starting place. The DH chunks seem to be loaded in a circle smaller than the set DH render distance.
