Autonav - aliases not showing

Permalink
I've found other posts that mention this being fixed in the next version of concrete5. But I still have this issue with 5.5.2.1.

I am creating a footer navigation using aliases. The issue i'm having is the aliases will not show. Same issue happens if I manually use an autonav block.

<?php
$bt_main = BlockType::getByHandle('autonav');
$bt_main->controller->displayPages = 'custom';
$bt_main->controller->displayPagesCID = '179';  
$bt_main->controller->orderBy = 'display_asc';                  
$bt_main->controller->displaySubPages = 'all';                 
$bt_main->controller->displaySubPageLevels = 'all';    
$bt_main->render('view'); 
?>
