Late to the party as one of my PC's is in the process of dying on days with a Y in the name, unfortunately the machine I use to listen to music on.
Today it is behaving, perhaps it heard I have ordered a replacement.
Obviously I am listening to the Mix/Remix? Sounds fine here on my Adams, everything is clear and present, no masking, no thumping, clear Vox, all the other voices can be discerned.
Nice job chaps.
As CbB is not really aware of what you have done in Melodyne you need to render region FX for it to do so.
When you open a region FX Melodyne you in effect transfer the audio to Melodyne.
You actually don't need it to be a region FX, If you drag the Audio up to the TimeLine Rule at the top CbB will extract the timing and apply it to the Tempo lane directly.
If you have Melodyne Editor or Studio you could try using the Tempo smoothing function in Melodyne to get a less jagged or jumping tempo map.
