AKEnvironment not working when player spawns inside the attached collider.

Question

I have three box colliders set up in a project to handle reverb zones: Exterior and two different Interiors. The box collider for the exterior covers the entire map and the two interiors are inside this collider, set to 'Exclude Others'. The two interiors work perfectly but the exterior does not trigger when the player spawns inside it. If I move the collider for the exterior to just outside of the player's spawn area it triggers as expected when the player moves into the Exterior collider, the issue only occurs if the player spawns in inside the collider. I thought setting the exterior to 'Default' on the AKEnvironment component would fix this but it makes no difference. What am I missing?
