Unable to reorder terms in custom taxonomy

I’m trying to get sorted terms from a custom taxonomy. The backend interface lets me sort the terms just fine, but when using code to fetch them, they’re not in the right order to match the backend ordering.

<?php
$my_custom_terms = new WP_Term_Query( [
	'taxonomy' 		=> 'my_custom_taxonomy',
	'order'    		=> 'ASC',
	'orderby'  		=> 'menu_order',
	'child_of'      => 0,
    'parent'        => 0,
    'fields'        => 'all',
    'hide_empty'    => true
] );

Am I going about this wrong? Thanks for your help!
