I'm trying to make a block that can drop 1 of 3 possible items if broken, but only drops itself when broken by a pickaxe with silk touch.
I got the 1 out of 3 part working fine, and the item does drop itself when i break it with silktouch but it drops one of those 3 items in addition to itself.
Here's my code.

{
  "type": "minecraft:block",
  "pools": [
    {
      "rolls": 1,
      "entries": [
        {
          "type": "minecraft:alternatives",
          "children": [
            {
              "type": "minecraft:item",
              "conditions": [
                {
                  "condition": "minecraft:match_tool",
                  "predicate": {
                    "enchantments": [
                      {
                        "enchantment": "minecraft:silk_touch",
                        "levels": {
                          "min": 1
                        }
                      }
                    ]
                  }
                }
              ],
              "name": "fossilsandstuff:cretaceous_fossil_deposit"
            }
          ]
        }
      ]
    },
    {
      "rolls": 1,
      "entries": [
        {
          "type": "minecraft:item",
          "weight": 33.3,
          "name": "fossilsandstuff:brachiosaurus_raw_fossil"
        },
        {
          "type": "minecraft:item",
          "weight": 33.3,
          "name": "fossilsandstuff:stegosaurus_raw_fossil"
        },
        {
          "type": "minecraft:item",
          "weight": 33.3,
          "name": "fossilsandstuff:allosaurus_raw_fossil"
        }
      ]
    }
  ]
}

Thanks.

The weight, by the way on that 1-of-3 thing, doesn't have to sum to 100. Its not a percentage, its a weight.

Not sure why the silk touch isn't working

You have two "rolls" which one is for the normal drops, and another roll for the silk touch, and they are not related. Means doesn't matter if the roll on the top succeed or not, it will always go for another roll for the normal drops at the bottom.

 children:

• For type 'alternatives' a list of entries of which the first, and only the first, successful entry gets generated.

But I have no idea about how to make it only drop one of them
