Custom Content Slider stop duplicate

I fixed it by removing all the items in the item class and adding a little

<?php $i=1; while ($i <= 1) { ?>
<div class="col-md-6 nopadding view view-ninth" style="padding-left:4px; padding-right:4px;">
                    <?php the_post_thumbnail('large'); ?>
                    <div class="content">
                    <h2><?php the_title() ;?></h2>
                    <p><?php $excerpt = get_the_excerpt(); echo string_limit_words($excerpt,15) . '...'; ?></p>
                    <a href="#" class="info">Read More</a>
                    </div>
                    </div>   <?php $i++;}?>
