dynmap: Newly generated chunks not rendering correctly without doing "/dynmap fullrender"

I’m not sure why but not all the chunks are getting rendered when they generate. However when I do /dynmap fullrender world it renders fine. The nether and the end appear to be unaffected as far as I can tell. I also noticed that when zooming in and out where the gaps are in the map seems to change slightly.

I’ve tried deleting the entire dynmap folder from my server’s plugins folder and then copying my config file over, which I’d recently deleted and regenerated as well. It seems the issue is still present.

/dynmap version:

Dynmap version: core=3.1-beta-1-367, plugin=3.1-beta-1-367

/paper version:
