Issue with chunks dissapearing instead of staying rendered.

I've been trying to get DH to work with big globe and a few other mods. It appears that when i'm walking away from chunks i've rendered, they'll disappear completely in adherence to the vanilla minecraft render distance. DH is on default Medium and Balanced settings with distance set to 256. It may be a simple setting issue or something but i can't seem to figure it out. I've attached my mod list. I have a 3080 TI and an! I9 12900H and 32 GB RAM.
