How to disable Bitcoind ZeroMQ notification publish block or transaction in mempool

TL;DR

zmq send the block data in mempool not confirmed in blockchain,how to filter these unconfirmed data.

the problem

In 2019 our production use blocknotify to fire event of new block,but this year(2020) I'm required to changed to using zeromq.So I change my code fired by zeromq's publish zmqpubhashblock , it's easy.But I found zmq send the block data in mempool not confirmed in blockchain, and not found anyother config can disable this behavior.

current node(a testnet btc node for development)

my code (a zmq sub demo in laravel command)

        $context = new \ZMQContext();
        $subscriber = new \ZMQSocket($context, \ZMQ::SOCKET_SUB);
        $subscriber->connect("tcp://192.168.1.136:28332"); //btc testnet
        $subscriber->setSockOpt(\ZMQ::SOCKOPT_SUBSCRIBE, "hashblock");
        // $subscriber->setSockOpt(\ZMQ::SOCKOPT_SUBSCRIBE, "hashtx");
        $subscriber->setSockOpt(\ZMQ::SOCKOPT_SUBSCRIBE, "rawblock");
        // $subscriber->setSockOpt(\ZMQ::SOCKOPT_SUBSCRIBE, "rawtx");
        $this->info("sub btc");
        while (true) {
            $multiRec = $subscriber->recvMulti();
            // if ($multiRec != false) {
            // var_dump($multiRec);
            $this->info(date('Y-m-d H:i:s') . ' rec:');
            $topic = $multiRec[0];
            $body = \bin2hex($multiRec[1]);
            $sequence = \bin2hex($multiRec[2]);
            $this->info("topic: " . $topic . " , sequence : " . $sequence);
            $this->info("body " . " , sequence : " . $sequence);
            $this->info($body);
            $this->info('----------------------');
        }

It output like this

I decode the rawBlockdata and get the txid a4268fe6e9e77cae4b74a99c1a50b0cc117d59fd0bd82444f9d829be0b97d73e, but it is zero confirmations (current 08:12:18 UTC Thursday, January 9, 2020).

check other testnet explorer solved my problem, the explorer I used is 200 behind current

By checking other testnet explorer, I find https://tbtc.bitaps.com/ is 200 block behind current (testnet January 9, 2020).

And the data is right now.(January 10, 2020).

It's not bitcoind's problem or my code's problem just check other testnet explorer.
