I am having some trouble with metadata for NFT I am minting. 

This is the asset on pool.pm:
https://pool.pm/asset1q6fku9qrfld526pfdm746qu3j7wtgvuh5xet9u

And again on adaptors.org:
https://adapools.org/transactions/3bec2e04ecf374d8d341f6d4ef38c2b1b70b1817cb2e6a9fa197b2aea7dd8de2/metadata

When viewing the asset on pool.pm it shows an error: 

    Error:
    Expecting an OBJECT with a field named `721`

But viewing it on adapools.org show that 721 tag is there. 

And this is the actual metadata submitted in the transaction. What am I doing wrong here? And why is it pool.pm showing an error?

    {
      "721": {
        "b767134d5185d7d7be2234855cc732c8b3b42d8b956b84244c83015c": {
          "TestNFT5": {
            "Name": "TestNFT #5",
            "Collection": "Multi-asset minting",
            "Description": "Used for testing multi-asset minting",
            "Mythic": "True",
            "Mythic Name": "Ancient",
            "Wizard Type": "Alcemist",
            "Ring Name": "Vollzabar",
            "mediaType": "image/jpg",
            "image": "ipfs://QmXEyaE9GQJ2Qbgzozjfb23drA5jaU9qXJu8jNPPxysZhu"
          }
        }
      }
    }

Any help will be appreciated!

Edit: Naturally, I have validated metadata before minting using https://pool.pm/test/metadata and no errors were shown.
