Ducking audio

Has Adobe recently made changes to the ducking audio/generating key frames? I was one version behind on updates, and updated yesterday. I used ducking audio today, and it was awful. It was either way too loud or way too quiet. It's a feature I use almost every day. Today's use of it was so bad that I just went through and keyframed myself the volume of the audio. Most of my stuff is pretty basic for a music bed; just duck the audio when there are voices. It's not hard to do manually, but the automatic was a time-saver. So, I wasn't sure if there was an update to it, and I no longer know how to use it properly.
