this is going to get confusing to explain but here it goes.
i believe one of the layers that is problematic (not the parent) may be the result of having to relink the layer (option-drag into comp to replace).
in the example, you'll see that each rotating person would be revealed with a name and the silhouette turns into a stylized image. To do so i required echospaces 'echos' to be independent. so i can go into a particular 'echo' and reveal the original image (without affecting the other silhouettes).
