Auto Generated Lightmap UVs Overlapping Error

Sorry if this is something basic, I’m quite new to unreal. I have a project with a cube grid mesh and wanted to bake lighting, yet when I do I get an “Overlapping lightmaps” error for the CubeGrid mesh.

I auto-generated the lightmap UVs, set the “Light Map Coordinate Index” to 1, and set the “Light Map Resolution” high enough that it’s green.
here is what UV channel 1 looks like

These are all the steps I saw online, so there’s got to be something I’m missing. All help is greatly appreciated!

I’m facing the same problem. Did you find a solution?

BTW, Unreal Engine 5.0.3, auto generated lightmap UVs
