Auto-ducking issue

Every time I utilize the auto duck feature in Audition in essential sound, it works great the first time around. However if I ever have to re-open that file, half of the tracks marked for ducking no longer do it. The tracks will play at full volume despite having the dotted line and all the settings marked correct. I end up having to adjust the duck amount in the essential sound to get it to kick back in. 

In addition, some of those tracks will simply not recognize the tracks they're ducking against. I have to go in and manually insert key frames across my file which completely defeats the purpose of the ducking.
