Breadcrumbs

Hello,

Thank you for contacting us and I am very happy to assist you.

From what I understand, you need to have a parent category and a child category in Breadcrumbs. Please correct me if I’m wrong.
But if that is what you are after then you need to customize your breadcrumbs in the front end adding the child category using the following filter:

/**
 * Filter to change the primary term output of the breadcrumbs class.
 *
 * @param WP_Term $term  Primary term.
 * @param array   $terms Terms attached to the current post.
 */
add_filter( 'rank_math/frontend/breadcrumb/main_term', function( $current_term, $terms ) {
	return $current_term;

And please make sure this is enabled on your Breadcrumbs:

I hope that helps and please do not hesitate to contact us back anytime if you require further assistance.

Happy to help!

Cheers,
