AME CC adds extra artifacts to my audio files

Hi all, here's my problem.

I'm using AME CC to batch encode alot of MP3 files to a lower bitrate. However, about 20-50% of the time, AME adds extra audio artifacts to the beginning of the audio file. Usually, AME will take the audio at time index 0:07, and put that as time index 0:00 of the audio file. This, of course is a terrible experience to the end user who will hear a "glitch" at the start of the audio playback. Below are links to download original files as well as AME corrupted files:

1. Original files: http://www.kaliki.com/_testing/originals/

2. AME encoded files: http://www.kaliki.com/_testing/encoded%20with%20AME/

Here's my specs:

AME version: 7.2.0.43

OS: Windows Server 2012

CC Subscription: yes

Other software running: Dropox, Python

Thanks
