Lightmap UV are overlapping

I get the message (I am typing this as is):
Object has overlapping UVs.
Lightmap UV are overlapping by 3.0%. Please adjust content - Enable Error Coloring to visualize.

How do I find this if its “None”. I click on it and nothing happens. I’ve had this happen with Static Meshes and it jumps straight to it. The other thing that’s driving me crazy is that this map only has 3 unique static meshes at this time. I’ve confirmed they are all fine. The rest is BSP, which suggests the problem is in the BSP. Any ideas?

Just in case you don’t believe me. This is what I get.

I just confirmed does mean BSP. I have another map created at the same time that has the same issue, but it has no static meshes at all.

I duplicated my level. Started deleting massive chunks of it until I started to get close. Then I deleted one at a time until I was left with 3 brushes. Deleting any one of the 3 fixes the issue. Two of the affected brushes were a part of a decoration so I converted the whole decoration to a static mesh. The new static mesh gave me the same error, but with the mesh name instead of none. I recreated the static mesh at the origin and finally the issue is solved.
