Seemingly Random Unwanted Silences on Audio Files

For some reason audition is silencing small segments of sound throughout my audio files.  I am working on a multitrack session.   It seems to be happening after I make edits.

I believe that it is happening when i merge two clips together e.g. after i delete a segment of audio and merge the remaining two clips together.  The silences are not happening at the point at which two sound clips merged, however they are happening minutes later in the audio.

I have attached a picture below in which I highlighted an unwanted silence on a voice file that was inserted mid-speech.  I highlighted the portion of sound that audition automatically silenced.

Any help would be much appreciated.
