Is patterning 2 using only mono samples?

I’ve been trying to make by own kits and I’ve noticed that that original sample sounds different if played in patterning 2. Original sample is stereo, but looks like it comes out mono from patterning. Here’s the comparison of wave-forms (top one is patterning, bottom is original sample):

Am I missing something, or all samples in Patterning 2 are mono? Is it possible to use stereo playback somehow?
