[Audition 2021 v14.1 Windows 10] Some WAV files open as blank?

I have several WAV files that I converted from MP4 videos using Switch Sound File Converter. The problem is that when I try to open those WAV files in Audition I just get Audition's blank gray screen, no wave forms, no errors. I would think the problem is the WAV files themselves, however they open fine in other apps including Audacity and REAPER. 

I've tried re-saving (exporting) the WAVs from Audacity, but Audition still treats them as though there's no content; Audition just displays a gray screen. While I'm sure to figure out a workaround, I'm curious: What is it about these WAVs (example attached) that Audition is being intolerant of while other (far less expensive) apps have no issue with?

Thanks.
