Unable to Track Stack

Hey there-

I recently made the switch to Logic Pro. I am trying to utilize the Track Stack feature, and in all of the help threads I find it says to right click on the track header and the option will appear. I have clicked around a bunch to make sure I'm clicking the correct location on the track header, but the option never appears.

I have alternatively tried to do it through the "track" menu, but most of the options are greyed out.

Any help would be greatly appreciated! This was one of the main features I was excited to utilize in Logic, and I'm stumped.

I've attached some screen shots so you can see what I'm looking at:
