Checkout Perch Shop

I'm having a lot of difficulty with perch and the checkout. I''m using paypal as a gateway and I don't understand why it's currently not importing the address. On my checkout page I have the following:

<?php 
if (perch_member_logged_in()) {

  // your 'success' return URL
  $return_url = 'https://tsm.web-design.wales/order-complete.php';
  $cancel_url = 'https://tsm.web-design.wales/cancel.php';
  perch_shop_checkout('paypal-express', [
    'return_url' => $return_url,
    'cancel_url' => $cancel_url,
  ]);


}else
{
    perch_members_login_form();

}
?>

The login form:

                            <div class="col-sm-6">
                                <div class="form-card">
