Mythic Crucible throwing NPE when a MM ItemStack is loaded

I have the following MythicMobs Item configured:

Wasserbeutel:
  ItemStack:
    ==: org.bukkit.inventory.ItemStack
    v: 2730
    type: POTION
    meta:
      ==: ItemMeta
      meta-type: POTION
      display-name: '{"extra":[{"italic":false,"color":"gold","text":"Wasserbeutel"}],"text":""}'
      lore:
      - '{"extra":[{"bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"dark_green","text":"Gewöhnlich"}],"text":""}'
      - '{"text":""}'
      - '{"extra":[{"italic":false,"color":"dark_gray","text":"Ein Beutel, gefüllt
        mit Wasser."}],"text":""}'
      potion-type: minecraft:mundane

This item is causing the following error in the console:
