Updating scores with "save online" does not change audio when checked

Upload a score (specifically using MDL drumline) with the "save online" feature, and click the "upload score audio"
At this point, it won't even upload the audio, but for a 2nd way to see it
Change a MDL drumline part in your score, and then update it through the same feature, and make sure "update score audio" is clicked, when done uploading, listen through the piece, the visual drum parts will change, but the audio will remain the old audio.
