Question regarding split output with headset


So i’ve gotten a very basic split output, headset going into one, and speakers going into the other.

But im not quite sure how I get it to work properly through Djay. Or maybe im just misunderstanding how it works.

When I press the headset icon on either track 1 or 2, I only hear the track through the right ear, and not the left. On the left ear I hear the track thats going through the speakers.

Is there anyway to get the track set to headset to play through both left and right ear?
