Can I edit more than one person in the image?
At the moment this is a limitation of the software. To edit a second person, save out the image after modifying the first person and then load it back in to work with the second person. You can stop the other person being distorted by using the repair tool (available in the shape tools section) and the revert tool (accessible by holding down shift while using the repair tool).
