Elements in php foreach can't be found

Hello,

I have a problem to find the section in php. The bolded code seems to be a problem to find.
What I need is to change the offer job or remove it at all.
I attached the code and image from the website:

<section class="container subpages">
  <div class="content">
    <h1 class="kariera">
      <?=$this->Lang("Kariera");?>
    </h1>
      <div class="info-parts main-info center-info">
          <p><?=$this->Lang("Dołącz do nas już teraz i pracuj z mistrzami digitalu!");?></p>
      </div>
    <div class="info-parts how-we-do">

      <?php foreach($this->jobOffers as $id=>$jobs): ?>
              <a href="<?= isset($jobs['link'])?"kariera/".$jobs['link']:'';  ?>" class="internal how-parts <?= isset($jobs['class'])?$jobs['class']:'';  ?>">
                <h3><?= isset($jobs['title'])?$jobs['title']:''; ?></h3>
                <p><?= isset($jobs['lead'])?$jobs['lead']."[...]":''; ?></p>
              </a>
          <?php endforeach; ?>

    </div>
  </div>
</section>

You are setting the AS to
as $id=>$jobs but only looking for $jobs.

I don’t have those offers saved in the code on server, so could it be sent by other API or saved somewhere else? How can i find it out?
