Automation Lines in Multi Tracks Dissappeared, I Have Searched Everywhere...

As it says.   I usually have the yellow lines (for volume) on my multis so I can do some quick automation on the audio clip its self in mulitrack view.  I know you can also do this by clicking the read button all the way to the left of each track which will bring down a window running the length of the track, but for volume this is just too time and space consuming.  The lines on the multis dissappeared last night and I can not for the life of me figure out how to get them back so I can automate volume on the multis themselves again. Any help would be GREATLY appreciated. Hope your all having a great day!
