Use Easy Load More with Custom Post Types

Hello,
I am using Easy Load More Plugin with custom post types. I have following COde

<div class="et_pb_portfolio_items_wrapper">
					<div class="et_pb_portfolio_items">
					<?php // query_posts('post_type=client_speak&posts_per_page=8');
					query_posts('post_type=client_speak');
					while( have_posts()) : the_post(); ?>
					<div class="et_pb_portfolio_item et_pb_grid_item csgridbox">
<a href="<?php the_permalink(); ?>"><span class="et_portfolio_image"><?php the_post_thumbnail('full'); ?>
<div class="playicon"></div>
</span></a>

<h2><a href="<?php the_permalink(); ?>">
<?php $client_designation=get_field('client_designation');
if($client_designation){ echo '<span style="font-size: 21px;font-weight: 400;">'.$client_designation.'</span>';}
?><?php //the_title(); ?></a></h2>
<p style="font-size: 16px;"><?php echo substr(get_the_excerpt(), 0,30); ?></p></div> 

					<?php endwhile;

					 ?>

					</div>
					<?php load_more_button();
					wp_reset_query(); ?>

Now When i click Load More button, Instead of Showing Next posts it repeats already visible post on page.
Please confirm where i am doing mistake.

Thank you.
