Audition decides all audio is silence despite being over my threshhold for what is audio

I don't know why this is happening, but I'm trying to remove all parts of a clip except for the talking using the diagnostic panel and the "remove silence" option. I kept moving my thresholds down to have Audition stop trying to tell me talking was silence, I had it at -57 db, above would be audio at 25ms, and below at 200ms would be silence. I don't know if these parameters are messing with it, but even audio that is -30 to -20 for multiple seconds is still considered silence. This seems like a major issue for what is an extreme time-saving feature. I just updated to the newest version last night and I am still having the same issues. I am also using a .wav file if that changes anything.
