Exponential Height Fog Disappears and Weird Horizon Line in Path Tracing Render

Hi, everyone, and happy Saturday (depending on where you live)!

As you can see in the attached still, I’m running into an issue where my exponential height fog disappears in the path traced render, and a weird line appears on the horizon (I presume it has something to do with the sky atmosphere).

Of course, in the Lumen render, those issues don’t exist.

Do you have any ideas on how I can fix the fog and horizon issue for path tracing to look more like the Lumen version?

PS I also attached a screenshot of my post-process volume, render, and cVars settings.

Any help would be much appreciated.

In order for the height fog to work in the path tracer, the volumetric fog option must be checked.
