Php 自定义帖子类型滑块不显示

自定义post类型owl滑块正确显示，我正在创建自定义post类型并使用owl转盘滑块注册功能，但短代码循环工作正常

自定义owl滑块短代码

function custom_owl($para,$content){
$para = shortcode_atts ( array(
'' => '',
), $para);ob_start();  
$cutting_slider = null;
$cutting_slider = new WP_Query( array ('post_type'     => 'custom_cuttingsystem','posts_per_page' => -1,'orderby' => 'rand'));
if($cutting_slider->have_posts()) {
while ( $cutting_slider->have_posts()) {
$cutting_slider->the_post(); ?>
<div class="owl-carousel owl-theme">
<div class="item">
<?php the_post_thumbnail ();?>
<a href="<?php the_permalink() ?>">
<h4><?php the_title(); ?></h4></a>
<span><?php the_category(); ?></span>
</div></div>
<?php }}
wp_reset_postdata();
$cutting_slider = null; return ob_get_clean();
}
add_shortcode ('owl-slider','custom_owl');

注册子主题owl函数排队脚本

function custom_owlcarousel() {

wp_enqueue_style('owlmin-css', get_stylesheet_directory_uri().'/owl/owl.carousel.min.css', 'all');

add_action( 'wp_enqueue_scripts', 'custom_owlcarousel' );
