If Ducking has Auto Keyframes on, it won't export the music track

Steps to reproduce:
    1. Have a music track with ducking turned on with automatic keyframes
    2. Export
 
Result: Video that’s fine, but music-less
Expected: Audio to sound like it did in Premiere

Workaround: Turn automatic keyframes off before exporting and it works fine.
