Hi Hector,
There are a few ways you can do this. Here's one way:
Open the Mixer and click on the 'ALL' tab. You should now see the Click channel strip (inst 256) in the Mixer.
Control-click on the Solo button of the Click channel strip to take it out of solo safe mode.
Turn the Metronome on.
Bounce the project.
:)
