WP Job Manager Resumes redirect after Resume Submission (or show apply if creating for application) when using WP Job Manager Field Editor

functions.php

<?php
add_filter( 'submit_resume_steps', 'replace_resume_done_with_redirect' );

function replace_resume_done_with_redirect( $steps ) {
    $steps['done'] = array(
        'priority' => 30,
        'handler' => function() {
		do_action( 'resume_manager_resume_submitted', WP_Resume_Manager_Form_Submit_Resume::instance()->get_resume_id() );
		$job_id = WP_Resume_Manager_Form_Submit_Resume::instance()->get_job_id();

		// Allow application
		if ( ! empty( $job_id ) ) {
			echo '<h3 class="applying_for">' . sprintf( __( 'Submit your application to the job "%s".', 'wp-job-manager-resumes' ), '<a href="' . get_permalink( $job_id ) . '">' . get_the_title( $job_id ) . '</a>' ) .'</h3>';
			echo do_shortcode( '[job_apply id="' . absint( $job_id ) . '"]' );
		} else {
			$dashboard_id = get_option( 'resume_manager_candidate_dashboard_page_id' );
			if ( ! empty( $dashboard_id ) && wp_redirect( get_permalink( $dashboard_id ) ) ) {
				exit;
			}
		}
        },
        'view' => null,
    );
    return $steps;
}

It seems that the echoed content renders before the wordpress header does!
