[Theme: Simple Catch] How to remove excerpt under slider

Hello,

I like to remove the excerpt and the title under slider. I already have a child theme. I have function.php in my child themes and write this code :

if (function_exists('simplecatch_sliders')) {

function simplecatch_sliders() {
	global $post;
	//delete_transient( 'simplecatch_sliders' );

	global $simplecatch_options_settings;
    $options = $simplecatch_options_settings;

	$postperpage = $options[ 'slider_qty' ];

	if( ( !$simplecatch_sliders = get_transient( 'simplecatch_sliders' ) ) && !empty( $options[ 'featured_slider' ] ) ) {
		echo '<!-- refreshing cache -->';

		$simplecatch_sliders = '
		<div class="featured-slider">';
			$get_featured_posts = new WP_Query( array(
				'posts_per_page' => $postperpage,
				'post__in'		 => $options[ 'featured_slider' ],
				'orderby' 		 => 'post__in',
				'ignore_sticky_posts' => 1 // ignore sticky posts
			));
			$i; while ( $get_featured_posts->have_posts()) : $get_featured_posts->the_post(); $i++;
				$title_attribute = apply_filters( 'the_title', get_the_title( $post->ID ) );
				$excerpt = get_the_excerpt();
				if ( $i == 1 ) { $classes = "slides displayblock"; } else { $classes = "slides displaynone"; }
				$simplecatch_sliders .= '
				<div class="'.$classes.'">
					<div class="featured">
						<div class="slide-image">';
							if( has_post_thumbnail() ) {

								if( $options[ 'remove_noise_effect' ] == "0" ) {
									$simplecatch_sliders .= '<span class="img-effect pngfix"></span>';
								}

								$simplecatch_sliders .= get_the_post_thumbnail( $post->ID, 'slider', array( 'title' => esc_attr( $title_attribute ), 'alt' => esc_attr( $title_attribute ), 'class'	=> 'pngfix' ) ) ;
							}
							else {
								$simplecatch_sliders .= '<span class="img-effect pngfix"></span>';
							}
							$simplecatch_sliders .= '
						</div> <!-- .slide-image -->
					</div> <!-- .featured -->

				</div> <!-- .slides -->';
			endwhile; wp_reset_query();
		$simplecatch_sliders .= '
		</div> <!-- .featured-slider -->
			<div id="controllers">
			</div><!-- #controllers -->';

	set_transient( 'simplecatch_sliders', $simplecatch_sliders, 86940 );
	}
	echo $simplecatch_sliders;
} // simplecatch_sliders
}

But the excerpt still in there, nothing change.
Anyone please help me

Thanks.
