I kinda get what Bandai Namco were trying to do with that, but it would have been far better if they had just added a "Both Arms" opinion and made the "Right Arm" and "Left Arm" options separate from each other. That way you would have the option to add a sticker to both arms or just one arm. ^_^Not only does it copy the sticker but also mirrors it.
