Plug in Roland TD-15 Drums but getting Piano sound

I have plugged in my Roland TD-15 kit into my computer and am using the TD-15 driver supplied by Roland. I can get it to trigger in n-Track under the MME - TD-15 option, but when I hit my kit, I hear the Piano trigger and not my drums. I have it plugged into my amp as well and I can hear my kit trigger correctly through the amp, but incorrectly through n-Track.

The weird part is, when I hit record, I can still hear the piano, but it’s capturing the drum sound. The annoying part is I can’t listen to the track and play at the same time because I hear the piano triggering throughout every time I hit a drum pad/cymbal.

Is there a setting I’m overlooking?
