WP Query for Posts (Products) in Specific Category that has 2 Specific Tags (*AND* both tags not *OR*)

This is really confusing me.

I’ve tried numerous things but cannot get appropriate results.

Here’s what I currently have for my query:

$  args = array(     'post_type' => 'product',     'tax_query' => array(         'relation' => 'AND',         array(             'taxonomy' => 'product_cat',             'field'    => 'slug',             'terms'    => array( 'ring' ),         ),         array(             'taxonomy' => 'product_tag',             'field'    => 'slug',             'terms'    => array( 'black', 'men' ),         ),     ), ); $  query = new WP_Query( $  args ); 

As you can see I am trying to return products in the product category ring that contain both the tags black AND men

It appears though the product_tag terms array which includes black and men, is returning posts that include the tag black OR the tag men in the ring category.

How do I get it so that only products that include BOTH the tags in the query are returned?

Thanks so much
