Chunks only generated with LODs have broken borders between other LOD-only-generated chunks

In the foreground of the picture (slightly to the left and just outside the normally rendered chunks) the ring of LOD chunks with unbroken borders have been generated by flying over them and loading them normally, while the chunks in the background (especially off to the right) with broken borders have only been generated by the LOD generator. Those with broken borders appear to have discontinuous heights between borders. The resulting gaps allow light to illuminate through them, resulting in the grid pattern seen in those chunks (much more noticeable during the day). I've only noticed it in ocean chunks as it's most noticeable with the lighting but I imagine it is an issue for others as well. No error messages appear, and the results have persisted after deleting and regenerating the LOD file.
