PHP cURL not showing a part of content from some point

I am struggling for a while to make this work but seems that I am missing something. The scenarios is this:
I am trying to get some informations from a website using PHP and cURL via DOMXpath query. I am getting any information till to a point and from that point and below i don't get anything...blank. The script that I am using is as below:

$target_url = "https[:]//[www][.]bankofalbania[.]org/Tregjet/Kursi_zyrtar_i_kembimit/"; //Remove [ and ] from url
$userAgent = 'Googlebot/2.1 (http://www.googlebot.com/bot.html)';

$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 1000);

$html= curl_exec($ch);
if (!$html) {
    echo "<br />cURL error number:" .curl_errno($ch);
    echo "<br />cURL error:" . curl_error($ch);
    exit;
}

// parse the html into a DOMDocument
$document = new DOMDocument();
libxml_use_internal_errors(true);
$document->loadHTML($html);
libxml_clear_errors();
$selector = new DOMXPath($document);

$anchors = $selector->query('/html/body/div[1]/section[1]/div/div[2]/div[2]/div[2]/div/table[1]/tbody/tr[1]/td[1]');
    foreach($anchors as $div) { 
        $value = $div->nodeValue;
        echo $value;
}

Intersting is that, if the $anchors is changed to this
$anchors = $selector->query('/html/body/div[1]/section[1]/div/div[2]/div[2]/div[2]/div/table[1]');
The content is extracted from the website. Also, I should mention that I have tried to change the query to something more direct, as below:

$anchors = $selector->query('//table[@class="table table-sm table-responsive w-100 d-block d-md-table table-bordered m-0"]/tbody/tr[1]/td[3]');

but the results are the same...null! I don't know what I am missing here but I can't make it run. What i am looking forward to get is the value of USD from the table of the page on $target_url.
Thank you in advance :-)
