[1.8] Keypress to open crafting table

I'm trying to have a keypress open a crafting table but whenever I do it the crafting table GUI is messed up in the sense that every item is one to the right of where I have to click to pick it up and placing items in the crafting table equips them to the player (depending on the slot).

public void onKeyInput(InputEvent.KeyInputEvent event) {

    if(KeyBindings.craftingButton.isPressed()){

        EntityPlayerSP player = Minecraft.getMinecraft().thePlayer;

        BlockWorkbench.InterfaceCraftingTable craftingTable = new BlockWorkbench.InterfaceCraftingTable(player.worldObj, player.playerLocation);
        player.displayGui(craftingTable);
    }

}
