Match Loudness Bug - empty files and fade in on random files

When I run the Match Loudness batch processing in Audition CC, i get at a random error, where  a few of the files are gained to 0 db (empty files) and, other random files will have a volume fade in. I typically batch process 30-100 files, and maybe around 5% of the files are affected. The ones that are gained to 0 dB are pretty easy to spot, but unfortunately not the ones that have a volume fade in. All the files are speech files originally at aroung  -20 to -30 dBLU

I am using Adobe CC with these settings.
