Channel Strip from concert level,doesn't apear at Set Level

Hello!

I am creating a MainStage 3 concert in Yosemite (10.10.3).

I have created a few channel strips with playback plug ins, and an audio track that is suppost to be my guitar input.

The problem is that when i create a new set (a song) or a new patch, the audio channel strip disappears...

Can anyone help me please?
