Textures become darker on BSPs when converted to a Static Mesh using Baked Lighting

A BSP converted to a Static mesh shows a much darker texture material when built with Static/Baked lighting.

This was reported and tested in 4.24.1 (CL-10757647). This was reproduced in 4.23.1 (CL-9631420) and Main 4.25 (CL-11028482)

1. Open the UE4 Editor and create a Blank project
2. Import a Texture into the Project
3. Create a Material with the Texture
4. Drag a Geometry Box into the Level
5. Apply the Material to all sides of the Box
6. Convert the Box into a Static Mesh (Details>Brush Settings>Show Advanced>Create Static Mesh)
7. Make sure its Mobility is set to Static and Build Lighting

Results: Textures are darker if using baked lighting

Expected: Texture to remain similar to how it was before lighting was baked
