Terrain brush being odd on on touched air

[DuckEater54]

So I had zoomed out, to move around and I zoomed in to this new area to check where I was in case of readjustment needed. I noticed a green thing on my screen, looked close and saw the words of chrome behind it.

This was on a brand new scene and project, immediately ran editor after generating and building the projects initially.

Shape: circle Radius: 4.000 Mode: modify height map Amount: 4.000

Ubuntu 22.04.1 LTS Fyrox-template 0.5.1 Gnome 42.5

Edit: It doesn't show the window behind it in Green on Skybox, it shows the green tinted window on the terrain itself, and I believe the reason why it looks like the skybox on the video is because I was looking at it from the other side perhaps. I am not sure. It will ONLY show on the green, in the brush it appears

My terrain node is default size, position and rotation, Static, within a Rigid body alongside a Collider
