Sound Attenuation radius doesn't affect the sound

Hi, I am dragging the sound cue to the level, then I am checking the “Override Attenuation” to make settings active. I edit inner radius and falloff radius to my needs. But it does nothing, sound starts to play as soon as I start playing the level and doesnt change the volume no matter where I am. I can start the game at the far end of the map but sound plays with no effect to attenuation. What am I doing wrong?
