"Exclude From HLOD Levels" has no effect in a World Partition level set up with HLODs

• Create a new wp map.
• Add a cube.
  • In the HLOD settings for it:
    • Should be included in HLOD
    • Set the "Exclude from HLOD Levels" to HLOD0.
• Make sure there's a "Default HLOD Layer" assigned (under World Settings > World Partition Setup).
• Build > Build HLODs
• Inspect the generated HLOD and notice the cube was included.

Tested with Instancing and Simplify. Approximate seems to work correctly.
