When leaving Audio volume, reverb continues?

Hi, UE4 noob here…

So I have an audio (reverb) volume covering the internals of a room, but when I leave the room, the footsteps continue play the reverb of the audio volume I’ve just left…?

So my questions are:

Have I encountered a bug?
Have I not specified something in the engine?
What can I do to amend this?

Cheers!

Late reply but I just had the same issue.

I found a workaround is to create another larger audiovolume that engulfs your existing audiovolume. Set the outer audiovolume reverb to zero gain and the inner audiovolume to a higher priority so it still works. You can adjust the reverb fade time on the outer audiovolume to control the speed that reverb fades back to nill.
