Advanced Custom Fields Group values are empty but wrapping element still visible

I'm building a Wordpress site using the Advanced Custom Fields. So now I only want to display these fields if they "exist" e.g. if they have content. I made this conditional statement:

$casemodule = get_field('case_page_instore');   

 if( $casemodule ) : ?>  
    <section class="block">
        <h2><?php echo $casemodule['case_header'] ?></h2>
        <p><?php echo $casemodule['case_subtext'] ?></p>
    </section>
<?php endif; ?>

So fa so good, If the fields case_header and case_subtext are empty, they will not be shown (obviously), but or some reason the <section>-tag is always visible, which is kind of strange since I followed the instructions on the ACF page.

Can someone maybe tell me what is going on?

UPDATE

I tried to do the var_dump($casemodule) and the result was:

array(2) { ["case_header"]=> string(0) "" ["case_subtext"]=> string(0) }

but that didn't solve anything

I solved it myself, the solution was:

if($casemodule['case_header'] && $casemodule['case_subtext']) : ?>

I simply removed the isset an voila! :-)

Thanks to Reza for the previous answer

Just because $casemodule['case_header'] and $casemodule['case_subtext'] do not exist, it doesn't mean that $casemodul won't exist. It could be an array that contains other keys or it could be just an empty array, which will exist!

Try to check if $casemodule['case_header'] and $casemodule['case_subtext'] really exist:

$casemodule = get_field('case_page_instore');   

 if(isset($casemodule['case_header']) && isset($casemodule['case_subtext'])) : ?>  
    <section class="block">
        <h2><?php echo $casemodule['case_header'] ?></h2>
        <p><?php echo $casemodule['case_subtext'] ?></p>
    </section>
<?php endif; ?>

If you are unsure about a variable, always use var_dump($variable), before you pass it to an if statement.
