Destroy Actor disables trigger volume - Why?

Unreal Engine 4.10 with FMOD 1.07.03

I’ve created a very simple pick-up item which is destroyed when the player overlaps with it. The item is located inside a trigger volume which activates an FMOD audio snapshot (with level changes and specific reverb settings).

The problem is that when the pick-up item is destroyed the FMOD snapshot disables and the audio returns to default settings (not good when I'm inside a house an all I hear is birds and traffic sounds).

 I would like to be able to walk around the room and collect a few of the pick-up items whilst the FMOD snapshot remains active.

Does anyone know how to fix this?
