Logic Pro X Export All Tracks Not Exporting All Tracks

My Logic Pro X is not exporting all tracks when I go to file, export, export all tracks as audio files. It begins to export all tracks (I know this because I can see all the tracks listed in the finder in the appropriate place I'm exporting to), but when it finishes exporting, it only exports maybe a hand-full of them and I only see 3 or 4, as opposed to the 20 I need to export.

Yes, they're all output to stereo. Yes, the MIDI channels are all on MIDI channel 1. Yes, I reinstalled. Yes, I rebooted. Yes, I can hear the audio in the DAW. Yes, they're not solo'ed or muted. Any ideas? The link provides a video I recorded of it happening. You might have to download it for high quality.
