Issue With Delete Silence But Retain File Length

Regarding the help page here: Waveform Editor diagnostics effects for Audition

Under the section "Delete Silence and Mark Audio options"

It says:

Fix By (Delete Silence only) .. "Choose Deleting Silence to mute silent passages but retain file length. (Deleting silence helps maintain video synchronization with audio clips in video editing applications.)"

However, when I use this option the file length is shortened and my video file is now out of sync with the audio file.

I tried installing all versions that were available to download in the Creative Cloud application and all behaved this way for me.

Has this option been changed? If so is there a way to still do this without manually selecting each section?
