Only show checked categories of Custom Taxonomy - php

Question

I am trying to display the names categories of a custom taxonomy called standard_engine_specification on a template page. This is what I have so far - it is showing all the categories of the taxonomy instead of just showing the ones checked in the admin panel.
<?php
/*variable to retrieve checked term*/
$ses_terms = get_the_terms( $id, 'standard_engine_specification' );
if( $ses_terms && !is_wp_error( $ses_terms ) ) {
foreach( $ses_terms as $term ) {
}
}
/*variable used to filter results*/
$ses_args = array(
'taxonomy' => 'standard_engine_specification',
'hierarchical' => true,
'tax_query' => array(array(
'taxonomy' => 'standard_engine_specification',
'field' => 'slug',
'terms' => array($term->slug),
'operator' => 'IN'
))
);
?>
<ul>
<?php
/*output checked categories based on filter*/
foreach (get_categories($ses_args) as $category)
{
echo "<li>";
echo $category->name;
echo "</li>";
}
?>
</ul>
I've pretty much Frankensteined this from some other scripts I have been using for filtering post types, maybe someone who knows what they are doing can tell me where and why I am missing this - I have put in some comments.

Ok sorted it. I did not need to use a tax_query, I tried to do the same thing I had done calling WooCommerce onto a template page but it was overkill, so we learn :)
<?php
$ses_terms = get_the_terms( $post->ID, 'standard_engine_specification' );
if( $ses_terms && !is_wp_error( $ses_terms ) ) {
foreach( $ses_terms as $term ) {
echo "<li>";
echo $term->name;
echo "</li>";
}
}
?>
