Weird persistent sky pillars within generated chunks

I am on a 1.21.1 server with DH 2.3.2-b and I keep getting these persistent sky pillars appearing in my LODs that won't go away. I've tried replacing the LOD data file for the server with an older copy that did not have the issues and the moment I join the server again the pillars come back again. There doesn't seem to be any way to make them go away.
