Sonus Depth - Pan in the Haas, issue

Hi, found issue in Sonus Depth PITH (Pan in the Haas). Delay knob not works it seems, i mean, during knob rotation is able to hear some respectively artefacts, but as result stereo image stay unchanged, as if works hard locked delay value. Seems not a big deal, since there is many way to do delay, but module looks pretty elegant (as SD loopers too - very liked), so, would be good to fix.
