When you use the menu used to select where you wish to 'warp' to, or to select what item to put a material on, if you have enough options you need to use the down arrow to see the second part of the list. Visually, the top of the second list is highlighted, but in reality, the top of the first list is what's highlighted, which tricks you into accidentally wasting a material change kit possibly unless you click the Already Visually Highlighted item on the second list.
