The "random behavior" seems like operations that are supposed to be applied to the grouped 3D boxes are instead applied to their gradients. Using the alignment tool to center the group horizontally and vertically only centers the gradients (causing color changes) on the 3D boxes, leaving the 3D boxes' positions unchanged.
