Leblanc's clone (RQ/RW/RE) doesn't do AA damage to dummies in training mode.

I'm pretty sure after playing a lot of games with LB that her RR clone does NOT do any damage but her RQ/RW/RE clone does do AA damage to champions. The weird thing is I feel like the clone does do dmg to champs I face in real games, but for some reason it never does any damage to the dummies at all. Is it a bug?
