(Not really a bug, just an adjustment that needs to be made)
To reproduce:
1. Open a new Unity project
2. Window --> Audio Mixer
3. In Master audio track, click "Add.."
4. Add SFX Reverb
5. In the Inspector Window, inspect the SFX Reverb Properties

Expected result: Room LF should be next to Room HF or Room HF should be next to HF Reference
Actual result: These properties look like they are all over the place (see attached picture "Screenshot_3.png")
