Rejected Submissions

So, I have had issues with inconsistent QC through VB for some time and would like feedback.  The issues I have been rejected for are "overprocessed", which is odd since I don't add processing at all, "muddy" or "boxy" sound.  

Please let me know what you hear that I'm not hearing.  I have put these in Adobe Audition with projects that have passed and I'm just not hearing what this QC screener is hearing.
