Missing metronome outputs in older songs

Does anyone know how to fix this? Some of my songs are two years old and when I open them, the metronome is gone, even though Halion Sonic or whatever is still there. Tick “Map always” but next time you open the song it will give the same error. Has anyone got this problem and how did you fix it please? Cubase Pro 10.0.10


Open Transport > Metronome Setup > General. In the Click Destinations make sure the the Use Audio Click is enabled. Click to the Audio Click Outputs and choose the output.
