OVRSceneManager placing Volumes above floor

Hey guys,

I have staged my room with the onboard software in the Quest 3's settings. This includes scanning the walls, doors, and adding in the furniture manually.

Once I use the OVRSceneManager component to load said scene into Unity, I see the walls in the correct places but most of the furniture is floating above the ground, along with one of them being clipped into the floor. 

I have checked:

-ScenePlane and SceneVolume are both barebones objects with the scripts exclusively, and one child with either a quad or cube with certain offsets applied as per the Meta docs.

-No other components exist on either object like rigidbodies or extra colliders.

-No additional offset is applied to the objects when spawned through their prefab or any parents in the scene.

Does anyone know why this could happen or experienced it in the past? Any information helps, thank you!
