Multiple Loot Filter Sounds

I'm not sure if this is normal but I'm getting multiple loot filter sounds on drops of currency items and maps.

This happens on the default loot filter aswell as Neversink's filter. Is there any way to just have one alert sound played?

/EDIT: I asked Neversink about that and apparently he didn't disable the default alert sounds. It's noticable since Incursion because GGG seems to have tinkered with their default alert sound volume. Neversink also told me that he'll be disabling the default alert sound with the next patch.
