$post is causing $loop = CFS()->get() to not work properly

This code on my static homepage displays recent posts:

<?php
   $postslist = get_posts('numberposts=10');
   foreach ($postslist as $post) {
      setup_postdata($post);
   ?>
    <div class="post-wrapper">
      <?php the_content(); ?>
    </div>
  <?php } ?>

…and in the next section on the page I am calling some custom fields from CFS including a loop. The above code causes the custom fields to not display their data, and I have narrowed it down to the issue being something to do with $post in the above code because when it is eliminated, the custom fields display their data properly. Here is the code for the custom fields.

<?php
    $loop = CFS()->get('questions');
    foreach ( $loop as $row ) {
  ?>
    <div class="faq content-col">
      <h6><?php echo $row['question']; ?></h6>
      <p><?php echo $row['intro_text']; ?></p>
      <?php echo $row['link']; ?>
    </div>
  <?php } ?>

Thank you in advance for your help! This forum has been AMAZING at helping with WordPress CFS.
