AAF export out of Premiere not showing keyframes

[Filmmaker78]

I'm exporting an AAF out of Premiere CC 2018. When I did it a few days ago, it worked fine and the audio keyframes showed up when the AAF was opened in Pro Tools. However, a new AAF from the same project now is showing up in Pro Tools without all of those keyframes, and the AAF file now is 10GB, while it was 16GB before. I don't think I changed the settings from before to now. Here are the AAF settings in Premiere - you can see the project's rubberbands in the audio files in the background.
