'Replace' not working on keys in another scene

Hi Frank,

I am trying to replace some key names across a few of my scenes.
It works correctly for all keys in the scene that is currently open, but if I go and find the same keys used in other scenes, they are all showing up as missing keys - still trying to look for the old one which no longer exists.
I have all scenes selected when I run the Replace parse, so it runs through all of them, but only successfully replace the keys in the current scene.

Any ideas?
