When dropdown is opened there is another container that opens up

Here is my link to the page. Please switch to mobile using IE and view the dropdown issue : http://3.131.234.17/database/

This is my code

          <form method="get">

            <?php

  $terms = get_terms([
    'taxonomy' => 'personality-database-category',
    'hide_empty' => false
  ]);
    
?>
            <select required name="personality-database-category[]"
              class="tw-border-black sm:tw-w-6/12 lg:tw-w-3/12 mul-select" multiple="true">
              <?PHP foreach ($terms as $term): ?>
              <option value="<?php echo $term->slug; ?>" <?php if(isset($_GET['personality-database-category']) &&
                in_array($term->slug, $_GET['personality-database-category'])){?>selected
                <?PHP } ?>>
                <?php echo $term->name; ?>
              </option>
              <?PHP endforeach; ?>
            </select>

            <?php

  $terms = get_terms([
    'taxonomy' => 'personality_type',
    'hide_empty' => false
  ]);
    
?>
            <br>
            <select required name="personality_type[]" class="tw-border-black sm:tw-w-6/12 lg:tw-w-3/12 mul-select2"

                slug, $_GET['personality_type'])){?>selected
                <?PHP } ?>>
                <?php echo $term->name; ?>
              </option>
