have you got your duplicates still?? if you have, heres how i wld tackle it.
1) go to animation editors > blend shape > delete...delete all
2) Go to your eye object, lets start with that.
select it and shift select the original, and go to deform > create blend shape > and click on the box.
3) in the options menu, rename it eyes or whatever u choose and click create.
4) Now, go to the second object, the mouth. select it and shift select the original. Go to Deform > create blend shape > and click the box .
Rename it mouth and click create. And voila.
The reason you probably had this under one is coz you may have clicked > ADD to blend shapes,
5) if you now go to window > animation editors > blendshape you should have to controls.
those who succeed are only the failures that never gave up.
