itemsadder material checking does not work

[slim dune]

i did something like this, but as soon as I click to download this emerald and give me blocks, something breaks and it doesn't check whether I have an emerald or not, but just gives me emeralds

  'emerald':
    material: itemsadder-emerald
    slot: 0
    lore:
      - 'test'
    left_click_requirement:
      requirements:
        has_item:
          type: has item
          material: itemsadder-emerald
          amount: 1
      deny_commands:
        - '[message] Nie masz tego przedmiotu!'
    left_click_commands:
      - '[console] iaremove %player_name% skyblock:emerald'
      - '[console] give %player_name% emerald_block 576'```
