WP_Query meta_key being changed by WHP

I have the following WP_Query that is suppose to get the 6 most recent broadcasts ordered by the Monday’s start date (monday_start_date is a custom field), but the results are in random order because WHP seems to be overriding the meta_key. WHP is not enabled on the Broadcast custom post type.

$args = array(
         'post_type' => 'broadcast',
         'posts_per_page' => 6 ,
         'order' => 'DESC',
         'orderby'  => 'meta_value_num',
         'meta_key' => 'monday_start_date',
);
$the_query = new WP_Query($args);
pr($the_query); // print_r wrapper

And here is a snippet of the output …

WP_Query Object
(
    [query] => Array
        (
            [post_type] => broadcast
            [posts_per_page] => 6
            [order] => DESC
            [orderby] => meta_value_num
            [meta_key] => monday_start_date
        )

    [query_vars] => Array
        (
            [post_type] => broadcast
            [posts_per_page] => 6
            [order] => DESC
            [orderby] => meta_value_num
            [meta_key] => _whp_hide_on_cpt_archive
            [error] => 
            ...
        )
...
)

Notice in the [query] section on the of the WP_Query Object the meta_key is set to what I asked it for, ie. “monday_start_date” but in the [query_vars] and key in [meta_query] sections it has been overridden with “_whp_hide_on_cpt_archive”. If I disable WHP then the meta_key and key revert to monday_start_date and WP_Query works as expected.

Current versions:
Wordpress 5.9.2
WHP 1.0.2

I have only just picked up on the issue but I have confirmed that it has only broken in the following update.

WHP 0.5.4 => 1.0.1

Please help.

Kind Regards,
Pete
