Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/SampleScene.unity” scene
3. In the Hierarchy View, click on “Cube (0)” GameObject
4. In the Inspector View, observe the Layer
5. In the Hierarchy View, click on “Cube(1)” GameObject
6. In the Inspector View, observe the Layer
7. In the Hierarchy View, click on “Point Light” GameObject
7. In the Inspector View, observe the “Culling Mask” under Light Components Rendering dropdown

Expected result: “Cube (1)” GameObject is not lit up when it has a layer different from the “Point Light” GameObjects' Culling Mask layer
Actual result: “Cube (1)” GameObject is lit up the same way as “Cube (0)” GameObject, although they have different Culling Mask layers
