Checking the transaction https://www.etherchain.org/tx/e12af4940879c634a63d2c9629449695e07650a4e419e5822ddb18d8469e9948 anyone can check there were 3 DigixGold token transfers.

These transfers are valued as 0 in etherchain as well as in amberdata.io: https://amberdata.io/transactions/0xe12af4940879c634a63d2c9629449695e07650a4e419e5822ddb18d8469e9948. In etherscan these transfers aren't even shown: https://etherscan.io/tx/0xe12af4940879c634a63d2c9629449695e07650a4e419e5822ddb18d8469e9948

If we check one of the log entries for this transaction we can spot this log entry related with the transfer function of the ERC20 token contract, and this transfer has a value different from 0 pictured in the last log's topic - source etherchain:

{
    "logindex": 0,
    "address": "0x55b9a11c2e8351b4ffc7b11561148bfac9977855",
    "data": "0x",
    "topics": [
      "0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef",
      "0x000000000000000000000000c5ec6937d3278311e2ace517df214717310c0820",
      "0x0000000000000000000000005d2c24efac49825f682b5d334428f1a5c96acc09",
      "0x0000000000000000000000000000000000000000000000000000000000043c36"
    ]
  }

Considering this log entry is related with one of the transfers and its not 0 valued, why in these browsers they are shown as 0 valued transfers? Is there any piece of information that should be missing in order to read and figure out about these transfers?

The target contract is a non standard ERC20 token.

It should have three topics, two indexed parameters and the event id and the transfer value in the data field. But it has four topics instead.

"topics": [
  "0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef",
  "0x000000000000000000000000c5ec6937d3278311e2ace517df214717310c0820",
  "0x0000000000000000000000005d2c24efac49825f682b5d334428f1a5c96acc09",
  "0x0000000000000000000000000000000000000000000000000000000000043c36"
]

Explorers fail in different ways while trying to cope with a non standard ERC20.
