Baked Lighting makes AO super strong

Steps:
1. Open "bakedtestlight" scene
2. The scene is baked with only 1 baked direction light

Actual result: The AO on the props are super strong, making the props look a lot darker.
Expected result: The lighting on the props should be the same with other 2 scenes in the repro project, which are using mixed / realtime directional light
