Problemas con saltos de página que mete por defecto

Buenas tardes:
Estoy haciendo una página con la theme SmartStart y cuando inserto un shortcode para hacer un slider me inserta por defecto 5 saltos de página y el slider se me queda muy abajo.
Os paso el código del propio slider que he cogido del shortcodes.php

/* -------------------------------------------------- */
	/*	Slider
	/* -------------------------------------------------- */

	function ss_framework_slider_sc( $atts, $content = null ) {

		extract( shortcode_atts( array(
			'id' => ''
			), $atts ) );

		global $post;

		$args = array('name'           => esc_attr( $id ),
					  'post_type'      => 'slider',
					  'posts_per_page' => '1'
				  );

		query_posts( $args );

		if( have_posts() ) while ( have_posts() ) : the_post();

			$output = '<section id="' . $post->post_name . '" class="ss-slider">';

				$slides = get_post_meta( $post->ID, 'ss_slider_slides' );

				if( !$slides || !$slides[0] )
					return;

				foreach ( $slides[0] as $slide ) :

					$output .= '<article class="slide">';

						if( $slide['slide-link-url'] )
							$output .= '<a href="' . $slide['slide-link-url'] . '" class="' . $slide['slide-link-lightbox'] . '">';

						$output .= '<img src="' . $slide['slide-img-src'] . '" alt="' . $post->post_title . '" class="slide-bg-image" />';

						$output .= '<div class="slide-button ' . ( $slide['slide-button-type'] ? $slide['slide-button-type'] : null ) . '">';

							if( $slide['slide-button-dropcap'] && $slide['slide-button-type'] != 'image' )
								$output .= '<span class="dropcap">' . $slide['slide-button-dropcap'] . '</span>';

							if( $slide['slide-button-title'] && $slide['slide-button-type'] != 'image' )
								$output .= '<h5>' . $slide['slide-button-title'] . '</h5>';

							if( $slide['slide-button-description'] && $slide['slide-button-type'] != 'image' )
								$output .= '<span class="description">' . $slide['slide-button-description'] . '</span>';

							if( $slide['slide-button-img-src'] && $slide['slide-button-type'] == 'image' )
								$output .= '<img src="' . $slide['slide-button-img-src'] . '" alt="' . $post->post_title . '" />';

						$output .= '</div>';

						if( $slide['slide-link-url'] )
							$output .= '</a>';

						if( isset( $slide['slide-content'] ) )
							$output .= '<div class="slide-content">' . do_shortcode( $slide['slide-content'] ) . '</div>';

					$output .= '</article><!-- end .slide -->';

				endforeach;

			$output .= '</section><!-- end .ss-slider -->';

		endwhile;

		wp_reset_query();

		return $output;

	}
	add_shortcode('slider', 'ss_framework_slider_sc');

He estado revisando el código final con la herramienta inspeccionar elemento de Chrome y me da este código, que no se de donde sale:

<section id="servicios" class="ss-slider show-content-onhover fully-loaded" style="max-height: 635px; max-width: 940px;">

<p><!-- end .slide --><br>
</p>
<p><!-- end .slide --><br>
</p>
<p><!-- end .slide --><br>
</p>
<p><!-- end .slide --><br>
</p>
<p><!-- end .slide --></p>
