Why does it only export the first 38 seconds of my "Original Recordings"?

I have a podcast episode I recorded online, 3 speakers (3 sources), and about an hour long. Whenever I try to export the original recordings, I get tiny 38 second-long files :(

I have the link (template, etc.) for it. I just need those files. 

Edit: I only want to export the audio,  not the video.
