Strange sound when using Kick presets pack 2

Just bought the Kick preset pack 2. When using it and every time a kick hits, there is also some sort of synth chord chime sounding in the background. It only happens with the preset pack 2 and all other kicks are as normal. Only plug in loaded is Kick so the sound cannot come from anywhere else. It seems to be a bug somewhere? What is the cause behind it? Im using OS Maverick.
