UPDATE:

I synced from this MacBook (where the previous issue occurred) to my iPad and then tried it from there. That appears to have exported the files fine with annotations. 

I noticed that the order was weird, and I think it might be because I had the "Use song page ordering for exported files" checked. But then when I uncheck that, the export crashes. 

So there's definitely a difference between MacBook and iPad. But there's also a couple of different checkboxes affecting the results here.

Thanks in advance!
