Using the audio mixer, trying to use the audio level arrows or nob to go lower than -24db does not change audio level below that point, even though it shows your desired value.

Trying to adjust lower than -24db does not yield a lower level of volume, but still displays your desired volume even though it does not go lower. For example, I was trying to lower the volume to -32db, but there was no difference in audio volume for the track.
