Tools equipping start to act weird in GUI?

So when I try to equip an item, it equips it normally and works. But when I select another item, it should make the text become "Equip" even though it stays at "Unequip". And once you select another item and press the Equip Button that says "Unequip", it'll make the tool disappear and make the new tool equip to the player. Does the same thing to other tools. They're all located in the "Swords" folder in my Backpack. But it seems to be that the item that disappears goes into the Backpack folder instead of the "Swords" folder.
