Orderby no longer working

Hi – I’ve been using LCP for years and just noticed that my category listings are no longer sorted alphabetically by category title. I’m not sure when it changed; maybe when I updated to php8?

Wordpress version: 6.0.2
PHP version: 8.0.23
LCP plugin version: 0.87

Shortcode with ID removed:
[catlist id=## post_type=page orderby=title order=asc excerpt=no numberposts=-1 template=listcat_template-lessons-main-subject excludeposts=this]

Template:

/* This is the string which will gather all the information.*/
$lcp_display_output = '';

// Show category link:
$lcp_display_output .= $this->get_category_link('strong');

//Add 'starting' tag. 
$lcp_display_output .= '<div class="noads">';

/**
 * Posts loop.
 * The code here will be executed for every post in the category.
 * As you can see, the different options are being called from functions on the
 * $this variable which is a CatListDisplayer.
 *
 * The CatListDisplayer has a function for each field we want to show.
 * So you'll see get_excerpt, get_thumbnail, etc.
 * You can now pass an html tag as a parameter. This tag will sorround the info
 * you want to display. You can also assign a specific CSS class to each field.
 */
foreach ($this->catlist->get_categories_posts() as $single):

	
	  //Create the header for the title:
    $lcp_display_output .= '<h4 class="topic-page-links">';
	
	  //Show the title and link to the post:
    $lcp_display_output .= $this->get_post_title($single);
	
	  //Close the header for the title:
    $lcp_display_output .= '</h4>';

      //Set the paragraph style for each post:
    $lcp_display_output .= '';
	
      //Post Thumbnail
    $lcp_display_output .= $this->get_thumbnail($single);
	
    //Show comments:
    $lcp_display_output .= $this->get_comments($single);

    //Show date:
    $lcp_display_output .= ' ' . $this->get_date($single);

    //Show author
    $lcp_display_output .= $this->get_author($single);

    /**
     * Post content - Example of how to use tag and class parameters:
     * This will produce:<p class="lcp_content">The content</p>
     */
    $lcp_display_output .= $this->get_content($single, '', 'lcp_content');

  
    /**
     * Post content - Example of how to use tag and class parameters:
     * This will produce:<div class="lcp_excerpt">The content</div>
     */
    $lcp_display_output .= $this->get_excerpt($single, '', 'lcp_excerpt');
	
    //Close li tag
    $lcp_display_output .= '';
endforeach;

$lcp_display_output .= '</div>';

	
$this->lcp_output = $lcp_display_output;
