Trial Spawner behaves differently if placed in creative or survival

I have created a custom trial spawner called the “ominous spawner”. The nbt data is the following:

"components": {
      "minecraft:block_entity_data": {
        "id": "minecraft:trial_spawner",
        "ejecting_loot_table": "custom:spawners/ominous/trial_chamber/consumables_and_key"
      },
      "minecraft:block_state": {
        "ominous": "true"
      },
      "minecraft:custom_name": {
        "text": "Ominous Trial Spawner",
        "italic": false
      },
      "minecraft:rarity": "epic"
    }

And here is the loot table of consumables_and_key in case you are wondering:

{
  "type": "minecraft:chest",
  "pools": [
    {
      "bonus_rolls": 0.0,
      "entries": [
        {
          "type": "minecraft:item",
          "functions": [
            {
              "add": false,
              "count": 1.0,
              "function": "minecraft:set_count"
            }
          ],
          "name": "minecraft:ominous_trial_key",
          "weight": 30
        },
        {
          "type": "minecraft:item",
          "functions": [
            {
              "add": false,
              "count": {
                "type": "minecraft:uniform",
                "max": 2.0,
                "min": 1.0
              },
              "function": "minecraft:set_count"
            }
          ],
          "name": "minecraft:cooked_beef",
          "weight": 21
        },
        {
          "type": "minecraft:item",
          "functions": [
            {
              "add": false,
              "count": {
                "type": "minecraft:uniform",
                "max": 4.0,
                "min": 2.0
              },
              "function": "minecraft:set_count"
            }
          ],
          "name": "minecraft:baked_potato",
          "weight": 21
        },
        {
          "type": "minecraft:item",
          "functions": [
            {
              "add": false,
              "count": {
                "type": "minecraft:uniform",
                "max": 2.0,
                "min": 1.0
              },
              "function": "minecraft:set_count"
            }
          ],
          "name": "minecraft:golden_carrot",
          "weight": 14
        },
        {
          "type": "minecraft:item",
          "functions": [
            {
              "add": false,
              "count": 1.0,
              "function": "minecraft:set_count"
            },
            {
              "function": "minecraft:set_potion",
              "id": "minecraft:regeneration"
            }
          ],
          "name": "minecraft:potion",
          "weight": 7
        },
        {
          "type": "minecraft:item",
          "functions": [
            {
              "add": false,
              "count": 1.0,
              "function": "minecraft:set_count"
            },
            {
              "function": "minecraft:set_potion",
              "id": "minecraft:strength"
            }
          ],
          "name": "minecraft:potion",
          "weight": 7
        }
      ],
      "rolls": 1.0
    }
  ],
  "random_sequence": "custom:spawners/ominous/trial_chamber/consumables_and_key"
}

You may ignore all the code above, it is just for reference.

The point here is that this trial spawner works when placed in creative but if the same custom spawner is placed in survival then the loot table used goes back to default.

In the following video I placed two spawners which are exactly the same but the only difference is that one is placed in survival and the other in creative. As you can see, the one placed in creative gives golden carrots (an item that is in my custom loot table and does NOT belong to the default trial spawner loot table) while the other one gives a trial key (an item that is not part of my custom loot table).
