After updating my Minecraft to version 1.16 official. Custom Block in my world has disappeared. I see code differences in behavior_packs/(behavior_packs.name)/blocks/(name).json

which in my file contains:

{
  "format_version": "1.12.0",
  "minecraft:block": {
    "description": {
      "identifier": "more:ruby_block",
      "is_experimental": false,
      "register_to_creative_menu": true
    },
    "components": {
      "minecraft:loot": {
        "table": "loot_tables/blocks/ruby_block.json"
       },
      "minecraft:destroy_time": {
        "value": 5
      },
      "minecraft:explosion_resistance": {
        "value": 30
      },
      "minecraft:map_color": {
        "color": "#ff0000"
      },
      "minecraft:block_light_absorption": {
        "value": 15
      },
      "minecraft:block_light_emission": {
        "emission": 0
      }
    }
  }
}

And in the other behavior pack (from Hidden Lights 1.16's Behavior Pack) it contains:

{
  "format_version": "1.10.0",
  "minecraft:block": {
    "description": {
      "identifier": "hiddenlights:blue_concrete_glowstone",
      "register_to_creative_menu": true,
      "is_experimental": false
    },
    "components": {
      "minecraft:destroy_time": 0.5,
      "minecraft:explosion_resistance": 20,
      "minecraft:block_light_absorption": 0,
      "minecraft:map_color": "#0000ff",
      "minecraft:block_light_emission": 1
    }
  }
}

Lots of differences between the two codes, eh? Perhaps the most obvious difference is in the format of the version where the format of the version in my code is 1.12 and in the other code is 1.10. Does the format version 1.12 in the file address no longer work with Minecraft version 1.16 official?
