Meta Value not Admin

Hi,
I am saving multiple meta values for a post.
One value is not displayed in the admin when I do this.

On the one hand I have once

update_post_meta( $leadid, "landingpage_links", $link_ids );
$links_ids is:  [0] => a:5:{i:0;i:9;i:1;i:5;i:2;i:1;i:3;i:6;i:4;i:3;}

and then once in a loop this

        foreach($iZero as $iZeroData){
            $metaImageName = 'images-'.$countIndex;
            update_post_meta( $leadid, $metaImageName, $metaurl.$iZeroData );
            update_post_meta( $leadid, "formCompletedImages", 1 );
            update_post_meta( $leadid, "formCompletedImages_Via", "EditForm" );
        }

Now when I look in the admin, all the meta values from the loop are shown to me, but “landingpage_links” is not shown to me there.

If I output get_post_meta(24766), I get everything displayed.

Here is a Screnshot what i mean with “not showing in admin”. The value “landingpage_links” not showing in this list.
