How to show tracks in the mixer view?

Please excuse this stupid question, but unfortunately I can’t figure it out at the moment:
We have an average of 5 to 10 tracks per song in our assembly, which doesn’t always fit on the screen. So I created two folders for each song and moved the tracks into them.
Question: How do I get ALL tracks displayed in the mixer at the same time?
I only have 4 tracks in my mixer view. what am I doing wrong here?

Thank you for your help.
