very easy fix, just go to the top of where your tracks are in the track view and youll see a little drop down menu.
switch this to all.
its called the track view filter I believe.
its also customizable, meaning you can choose what you'd like to see in your tracks.
too many things in your tracks boxes ?
customize will let you pick and choose what you see.
different tracks have different options as well, midi, audio,exc.
