When I use Smart Fit for Duration to extend an audio clip to the length of my project, the final rendered audio clip has several squiggly lines (breaks) in the audio. Each one of these breaks results in a noticeable skip in the sound during playback. To reduce the number of these breaks, I move the Bias slider to the right and try to get the breaks to at least 1. However, even this one break in the final rendered version results in a skip in the sound during playback. Is there a way to completely get rid of these breaks in the audio when using Smart Fit for Duration? Or at least adjust the final rendered version to remove the "skip" in the sound during playback?
I have attached a screen shot showing the output with the squiggly line (break) in the audio and where I had to set the Bias slider to get the the breaks down to only one break in the final rendered version. I also tried moving the slider all the way to the right to completely remove the one break, but it did not remove it.

I would appreciate any help to resolve this, as I need to use Smart Fit for Duration on every project I am working on and will have this sound skipping problem on each one.
