Melodyne - no audio after re-recording clip

I'm encountering a problem when using Melodyne that I hope is just my lack of knowledge of how it works.
 
Here's my process -
I record a vocal clip. I insert Melodyne in the FX bin of the track and then use it to adjust the tuning. So far so good.
However, I then decide I'll scrap that clip and do a re-take, so I delete the clip from the track. But I can still hear the vocal clip, so I go into Melodyne and select & delete the adjusted notes.
Great, now it's gone, I can't hear anything. So I re-record the vocal take, but now I can't hear the new clip even though I can see it's there.
Can someone please enlighten me as to where I'm going wrong?

Try using Melodyne as Region FX instead of the FX bin. To do so right-click on the clip and load it into Region FX > Melodyne > Create Region FX or select the clip and use the same path from the Track view Region FX menu.

Nope, that doesn't appear to help any. I'm still not hearing the clip, but that's presumably because I still have Melodyne in the FX bin - I have earlier clips in the track which are already edited and I'll lose these edits if I delete Melodyne. 
 
If I drag the clip along the track a bit I can then hear it but of course it will be in the wrong place!
It seems the region from where I've deleted the notes in Melodyne can't now be re-recorded over. 
 
Lesson learnt today is Don't Place Melodyne in the FX Bin
