[Support request] One Shortcode Doesn’t work

Hi Team,

I have created a shortcode, which is not working. But other custom shortcodes working perfectly.

I just showing you my shoercode codes:

function dl_minti_button_shortcode($atts, $content = '') {
	extract( shortcode_atts(
        array(
            'link' => '#',
            'target' => '_blank',
            'lightbox' => '',
            'color' => '',
            'icon' => ''
        ), $atts )
    );

  	ob_start();
  	?>

  	<div class="minti_butto_wrap">
  		<a href="<?php echo $link; ?>" target="<?php echo $target; ?>"><?php echo $content; ?></a>
  	</div>

  	<?php
  	return ob_get_clean();
}
add_shortcode( 'minti_button', 'dl_minti_button_shortcode' );

I have applied this shortcode in this page https://justcreative.com/shortcode-test-page/

But showing me plain shortcode text. See screenshot http://i.prntscr.com/8Dm_8e8bRRixNvkW2IqMgQ.png

So, please me how can I solve this problem.
