Overlapping Uv/ Lightmap

I couldn’t see this in your images in the details panel on the right, but make sure that you’ve set the Lightmap Coordinate Index to 1 and that it’s not set to 0.

You can do this by going to the details panel on the right > Static Mesh Settings > Advanced rollout > Lightmap Coordinate Index.

It looks like you have a good Lightmap set up on UV Channel 1.

This section on our Wiki Lighting Troubleshooting Guide should help explain the settings for generating lightmaps and setting them properly.
