I have a DoL vest that I made and attached 2 materia onto. One materia was for GP, the other had +3 perception. But when I equip the item, I get the message "materia and aetherial attributes could not be restored." Also, in my gear set list, there is a warning sign. When I mouse over, it reads "one or more items were not melded with the specified materia."

What did I do wrong?
