Solved For-loop bug

I've tried to use a for-loop to go through all of the shops display the corresponding material and price. The void to start this is:

Code:

    private void NewGUI(Player p, int shopID) {
    inv = Bukkit.createInventory(null, 27, "§a§lShop " + shopID);
    for(int i = 0; i < shops[shopID].length; i++)
    {
        i = shops[shopID].length - 1;
        if (shops[shopID][i] != null)
        {
          if (sellPrice[shopID][i] > 0)
          {
            inv.setItem(shopID, new CustomItem(shops[shopID][i], "", Arrays.asList("§4Right click to Buy (§1$" + buyPrice[shopID][i] + "§4)", "§4Left click to Sell (§1$" + sellPrice[shopID][i] + "§4)")));
          } else {
            inv.setItem(shopID, new CustomItem(shops[shopID][i], "", Arrays.asList("§4Right click to Buy (§1$" + buyPrice[shopID][i] + "§4)", "§4You can't sell this item.")));
          }
        }
    }
    inv.setItem(26, new CustomItem(Material.GOLD_INGOT, "§6Balance: $" + (int) econ.getBalance(p) ,Arrays.asList("§4Click to Exit!")));
    p.openInventory(inv);
    }

The output for the loop is weird like so:

Code:
