Hierarchy display setting is saved as null

Hello,

I am working on upgrading the breadcrumb plugin from 5.2.0 to 7.2.0 and it seems that checking the option Show the hierarchy (specified below) leading to a post in the breadcrumb trail gives a null whenever I var_dump it.

To test, you can add this line in class.bcn_breadcrumb_trail.php as the first line of the method post_hierarchy():

$this->opt['bpost_' . $type . '_hierarchy_display'];

If the option is unchecked we get a false, which is expected, but if the option is checked, it dumps a null.

Since null is a falsy value, I can’t have my date breadcrumbs showing without tampering the first condition in post_hierarchy.

Am I missing something ?

Thanks for reading me.
