Metronome Click on X1622 USB Mixer

I just got this XENYX X1622 USB Mixer. I got the latest ASIO driver, installed, tested and everything appears fine. I could record and playback with it. The only problem is I can’t hear the metronome click, even though it records. I did the metronome setup and made sure to enable it (turn it ON) I even specified how many bars it should click before recording. Still, no metronome sound. How do I get the metronome click to come out please? Thank you.

EDIT. Problem solved. Quite a few buttons on the mixer, and it takes some getting used to.
