track not showing up when the source file is in all the other tracks around it

Hi,

Check out the image attached. I'm opening a file from last year. The tracks around this purple one show the file that should be showing up in my track. It's there and the other files play correctly. I can click on this track and go to source file and it will play, but it's not showing up in the multitrack, and I need that to show up so I can mix it down again. Why would that not show up? I feel like it's a bug, and it kinda stinks because that is the track that I need.
