help editing sifz files???

I must be doing something wrong when i open a saved sifz i am unable to transform any of the ducks or edit any parameters? please help? i get this error message :
The value you are trying to edit is in a composition
which doesn’t seem to be open. Open that composition and you
should be able to edit this value as normal.

If you’re using an imported sifz file inside another composition, you need to open the imported sifz file separately, rather than trying to drill down into it from the layer menu. Any changes you make will show in the parent sifz file as you make them.
