Unknown listener game object ID - UE4

Question

I'm working with 4 Spatial Audio Volumes that are next to each other and "connected" through doors, where I added Acoustic Portals. Every time I get into one of those volumes I get this message:

"Unknown listener game object ID. Make sure the game object is registered before using it and do not use it once it was unregistered."

It always happens with the same volume. Any ideas?

I'm working on Unreal Engine 4.17.2
