ShopGUIPlus wont let me add ZombiePigman Spawners?

[YourPanda]

Hi, I am trying to add ZombiePigman Spawners to my ShopGUIPlus, under the Spawner Section, but it will not add. This is what happens:

As you can see, there is just an empty spot. And, this is what I have in the config. And, I am not sure what I am doing wrong.

      5:
        type: item
        item:
          spawner: true
          mob: ZombiePigman
          name: "&dPigman"
          quantity: 1
        buyPrice: 300000
        sellPrice: -1
        slot: 4

If you can help me figure this out, that would be great.



Best Regards,
