Comments wrapped in tags

Hello,

Can somebody let me know why this function

function edd_checkout_cart() {
do_action( ‘edd_before_checkout_cart’ );
echo ‘<!–dynamic-cached-content–>’;
edd_get_template_part( ‘checkout_cart’ );
echo ‘<!–/dynamic-cached-content–>’;
do_action( ‘edd_after_checkout_cart’ );
}

when it is echoed out wrap the comment like that:

<p>
<!–dynamic-cached-content–>

</p>

The p tags is messing my design making the title and the checkout_cart content having too much space!

Is there a way to force wordpress to display the content as just a comment?

Thank you all in advance,
Nick
