Edit the output of a filter

Question

I'm trying to edit the output of the filter (below) in the plugin WPJobManager. I want to make sure there isn't a duplicate company_name value in the $job_slug before it is updated. At the moment, its set to add company_name to the slug, but if you then edit the same post, it adds company_name again!

if ( apply_filters( 'submit_job_form_prefix_post_name_with_company', true ) && ! empty( $values['company']['company_name'] ) ) {
        $job_slug[] = $values['company']['company_name'];
}

I think I need to add a filter in my functions.php but I'm not sure how to do this with an IF statement to remove the duplicate. I was thinking something like this below? Could anyone point me in the right direction?

if ( strpos( $job_slug, sanitize_title($values['company']['company_name'];) ) ) {
            return;
        }

i have created the following solution, it is working when you keep into the active theme functions.php.

Page: includes\forms\class-wp-job-manager-form-submit-job.php
Line: 791

add_filter('submit_job_form_save_job_data', 'remove_dublicated_post_name', 10, 5);

function remove_dublicated_post_name($job_data, $post_title, $post_content, $status, $values){
 if( ! strpos( $job_data['post_name'] , sanitize_title($values['company']['company_name'] ) ){
    // to remove dublicate company names
    $post_name_raw_arr = explode("-",$job_data['post_name']);
    $post_name_unique_arr = array_unique($post_name_raw_arr );
    $job_data['post_name'] = sanitize_title( implode( '-', $post_name_unique_arr ) );
  }
return $job_data;
}
