[Plugin: Advanced Custom Fields] One value in a none-required fields gets looped out in every post

Hello, this might just be a lack of php skill from my side but i thought id post my problem here since you guys hopefully have some more understanding of my problem.

I have a post type called Reseller which contains acf for name, phone, mobile, fax, email, adress etc. Some of these fields are not required for input (fax, mobile, etc), and others are. My problem is that when i put a mobilenumber on one reseller that number gets looped out on every reseller… See the code below

global $post;
$tmp_post = $post;
$empty_array = array();
//setup the query
$args = array(
			'post_type' => 'reseller',
			'meta_key' => 'gw_reseller_name',
			'orderby' => 'meta_value',
			'order' => 'ASC',
			'numberposts' => '-1',
			'meta_query' => array(
						array(
								'key' => 'gw_reseller_zip',
								'value' => $thetitle
							)
						)

				);
// get posts according to $args
$custom_posts = get_posts($args);

foreach($custom_posts as $post) : setup_postdata($post);
	echo "<ul class=\"reseller_wrapper\" id=\"reseller-"; the_field('gw_reseller_name'); echo "\">";
	get_reseller();
	echo "</ul>";
endforeach;
//reset
	wp_reset_postdata();
	$custom_posts = $empty_array;
	$post = $tmp_post;

the function get_reseller() looks like this:

function get_reseller() {

// variables that might come in handy later... only for testing
	global $gw_lev_name_var, $gw_lev_adress_var, $gw_lev_postadress_var, $gw_lev_telnr_var, $gw_lev_fax_var, $gw_lev_mobile_var, $gw_lev_mail_var;

	$gw_lev_name_var = '<strong><li class="gw_lev_name">' . get_field('gw_lev_name') . '</li></strong> ';

	$gw_lev_adress_var = '<li class="gw_lev_adress">' . get_field('gw_lev_adress') . '</li> ';

	$gw_lev_postadress_var = '<li class="gw_lev_postadress">' . get_field('gw_lev_postadress') . '</li> ';

	$gw_lev_telnr_var = '<li class="gw_lev_telnr"> Tel: ' . get_field('gw_lev_telnr') . '</li> ';

//These are none-required fields, hence the check if null

	if(!(get_field('gw_lev_fax') == null)){
		$gw_lev_fax_var = '<li class="gw_lev_fax">Fax: ' . get_field('gw_lev_fax') . '</li> ';
		}

	if(!(get_field('gw_lev_mobile') == null))
		$gw_lev_mobile_var = '<li class="gw_lev_mobile"> Mobil: ' . get_field('gw_lev_mobile') . '</li> ';

	if(!(get_field('gw_lev_mail') == null))
		$gw_lev_mail_var = '<li class="gw_lev_mail">E-post: ' . get_field('gw_lev_mail') . '</li> ';

  	echo $gw_lev_name_var, $gw_lev_adress_var, $gw_lev_postadress_var, $gw_lev_telnr_var, $gw_lev_fax_var, $gw_lev_mobile_var, $gw_lev_mail_var; 

}

Now, this code is reduntant and in swedish atm but it’s just for making things work before i make it more efficient. Any ideas?
