Clips with audio keyframes play at incorrect level

Since around an update around a year ago, whenever I open my project up (documentary feature +2 years of work) and play anywhere on the sequence, if the audio clip playing has keyframes in it, which many of them do, the clip will start playing the clip at an extremely low volume until it hits the keyframe - then it plays at the correct volume. I end up having to scrub through the entire hour+ film and hit all of those keyframes before I want to show it to my client every time I open up the project again. Once I do this once it sticks until I close the project again. It is as if the audio gain I've added through the "Adjust Gain by" function (which I do for almost every clip as part of my workflow when I first sync the footage) is being "forgotten" by the program until I hit that first keyframe. This problem does not exist with clips that have no keyframes. I have been living with this problem for a while, hoping Adobe fixes it in the next update, but keep being dissappointed. So in case anyone else has this problem, help!
