why can't I hear my click?

Hi, I’m running Essential 5 and I have what I suppose is an initial setup issue. Consider me a newbie. I can hear the metronome click through my computer when I go to metronome setup and select Microsoft GS Wavetable Synth in the Midi/Port Channel box. But I don’t get the click if I select my interface - Lexicon Lambda Midi. I want to hear it from the interface so I can hear the click and what I’m recording from the headphones that are plugged into the Lexicon.
Thanks very much.
