NavMeshBoundsVolume as ChildActorComponent

Hello.
I am trying to get several Characters, as ChildActorComponents, to interact with a NavMeshBoundsVolume, that is also a ChildActorComponent.

I have tried both manually adding the NavMeshBoundsVolume to the parent Actor, as well as adding it in ConstructionScript, with AddChildActorComponent, but with no success. The NavMeshBoundsVolume appears to be created, but not to interact with the landscape of the map its parent Actor is placed in.

Note that I am not trying to update this NavMeshBoundsVolume at runtime. I only need for my blueprint to make some calculations about size, and apply them to the NavMeshBoundsVolume, during editing.

Any help is appreciated.
