I don't know. I think you selected stuff in wrong order. Or maybe you haven't got rid of translational part of that single placement.
I often goof up selection order myself. I should make a task dialog, but I'm unfamiliar with how to make them, and it will take probably more time than it took to implement the actual feature
EDIT: BTW, big thanks for interest.
