Stereo output channel problem(NI Battery 4)

Hi Guys,

I need to fix a problem regarding Battery 4 Multiple Stereo outputs. I have set my kick cell to one of the multi output channel (St 3/4 but) when i click on the track i cant play the kick on my midi controller( I press the key but nothing happens). However, when i click my main channel track, i am able to play all my drum samples. So how do i make it so that when i select one of the multiple outputs (e.g. st3/4), I am able to press my kick and it plays??? Thanks!
