thermal ores dont want to spawn in other stone types like ad astra mars stone

What am I doing wrong? I want ores from the Thermal Foundation mod to spawn on the Adastra Mars, even if the ore is in a different rock. I don't care for now, it's just a visual i think.
This is my biome_modifier in path "datapacks\Ore_Worldgen\data\thermal\forge\biome_modifier\ore_silver.json":
{
  "type": "forge:add_features",
  "biomes": "ad_astra:martian_wastelands",
  "features": "thermal:silver_ore",
  "step": "underground_ores"
}
this is my configured_feature in path "datapacks\Ore_Worldgen\data\thermal\worldgen\configured_feature\silver_ore.json":
{
  "type": "minecraft:ore",
  "config": {
    "discard_chance_on_air_exposure": 0.0,
    "size": 8,
    "targets": [
      {
        "state": {
          "Name": "thermal:silver_ore"
        },
        "target": {
          "predicate_type": "minecraft:tag_match",
          "tag": "is_mars:is_mars_stone"
        }
      },
      {
        "state": {
          "Name": "thermal:deepslate_silver_ore"
        },
        "target": {
          "predicate_type": "minecraft:tag_match",
          "tag": "is_mars:is_mars_stone"
        }
      }
    ]
  }
}
and that my placed_feature in path "datapacks\Ore_Worldgen\data\thermal\worldgen\placed_feature\silver_ore.json":
{
  "feature": "thermal:silver_ore",
  "placement": [
    {
      "type": "minecraft:count",
      "count": 4
    },
    {
      "type": "minecraft:in_square"
    },
    {
      "type": "minecraft:height_range",
      "height": {
        "type": "minecraft:uniform",
        "max_inclusive": {
          "absolute": 40
        },
        "min_inclusive": {
          "absolute": -60
        }
      }
    }
  ]
}
the tag "is_mars:is_mars_stone" contains the block Mars Stone in a datapack and looks like this in this path ""datapacks\Tags\data\is_mars\tags\blocks\is_mars_stone.json":
{
  "replace": false,
  "values": [
    "ad_astra:mars_stone"
  ]
}
but it doesnt work and the ore doesnt spawn on the mars mplanet from ad astra
