Collections list not complete in Collections tab

here's part of the diagnostic report - what looks odd is the <?php just after the runtimes, not sure if this is normal. Not sure if there's a secure way to share the full report - I'm not keen on exposing my server specifics in a public forum.

I've updated to the latest version. Still same issue.

I see pagination controls in the "listing all assets" area.

I've edited the collection.list.post.php file to include the paging function I lifted from the asset area to be the following:

It works as expected now.

<?php include (PERCH_PATH.'/core/inc/sidebar_start.php'); ?> <p><?php //echo PerchLang::get(''); ?></p> <?php include (PERCH_PATH.'/core/inc/sidebar_end.php'); ?> <?php include (PERCH_PATH.'/core/inc/main_start.php'); ?> <?php include ($app_path.'/modes/_subnav.php'); ?>

<?php if ($CurrentUser->has_priv('content.collections.create')) { ?>
<a class="add button" href="<?php echo PerchUtil::html(PERCH_LOGINPATH.'/core/apps/content/manage/collections/edit/'); ?>"><?php echo PerchLang::get('Add collection'); ?></a>
<?php } // content.collections.create ?>

<h1><?php echo PerchLang::get('Listing all collections'); ?></h1>

<?php
/* ----------------------------------------- SMART BAR ----------------------------------------- */

/* ----------------------------------------- /SMART BAR ----------------------------------------- */
$Alert->output();

echo $HTML->listing($collections, 
        array('Title', 'Items', 'Updated'), 
        array('collectionKey', 'get_item_count', 'collectionUpdated'), 
        array(
                'edit' => '../../collections',
                'delete' => 'delete',

            ),
        array(
            'user' => $CurrentUser,
            'edit' => 'content.collections.manage',
            'delete' => 'content.collections.delete',
            'not-inline' => true,
            )
        );


        if ($Paging->enabled()) {
            echo '<div class="paging-cont">';
            echo $HTML->paging($Paging);
            echo '</div>';
        }
?>

<?php include (PERCH_PATH.'/core/inc/main_end.php'); ?>
