Fade out on a single track isn't working

I'm mixing a few tracks together, and I'm using the Automation fade in and fade out features to do this. It's working great on one of my tracks (the "Say it Ain't So" track that's fading in, in the screenshot) but it's not working for the other track (the "Come on Over" track that's fading out, in the screenshot). "Come on Over" is continuing to play at full volume, even though I've faded it out. Please help!
