Export to WAV or MP3 from a part (not the main score) seems to ignore 8va.

I have a choral score with piano and strings I'm working on, and so I'm generating several different parts (Conductor, Choir, Strings, Percussion, etc).

The Conductor part, is not the same as the master score, as it leaves out a few staves I don't want the conductor to have to worry about (like a piano reduction).

So I wanted to render the conductor part to a WAV file, and when I did, I noticed a few things.
- The audio mix doesn't quite seem the same as when playing the part back in the editor directly. Some instruments seemed much quieter.
- The 8va I have over a few small piano licks are not playing it the octave higher when exporting the Part.

I was able to get around this by exporting the WAV from the main score, rather than the conductor part, and it worked as expected. I do feel however that exporting the audio rendering of any particular part should match the playback as heard in the editor.

Image attached shows the particular moment. The 8va exports as expected from the main score tab, but does not apply the 8va when exported from the Conductor part.

The 8va notes are on Voice 1.
