javascript - 为什么 eth.contract.Transfer 只返回选择的交易？

Question

我正在尝试获取 ERC-20 令牌的所有传输事件。但是使用 web3.contract.event.eventName 只返回大约 12 小时前的选定事件。我哪里错了？

当前区块是：8514062；但我得到的最新交易是块 8510432

tokenContract.events.Transfer({
    fromBlock: 8510000,
    toBlock: 'latest'
}, function (error, events) {
}).on('data', function (event) {
    console.log(event);
})

我关注的地址：0xB8c77482e45F1F44dE1745F52C74426C631bDD52

我得到的最后一笔交易：
