"I do not see the correct default output" - switch statement exercise

Why am I getting error message "I do not see the correct default output" for the switch statement exercise?

switch.php 
<?php
//Available roles: admin, editor, author, subscriber
if (!isset($role)) {
    $role = 'subscriber';
}

//change to switch statement
$role = "admin";
switch ($role){
  case "subscriber":
    echo 'You are a subscriber and do not have access to this page.';
    break;

  case "author":
    echo 'You are an author and do not have acccess to this page.';
    break;

  case "editor":
    echo ' You are an editor and do not have access to this page.';
    break;

  case "admin":
    echo 'You are an administrator. Welcome.';
    break;

  default:
  echo "You do not have access to this page. Please contact your administrator.";
}

if ($role = "admin"){
  echo 'As an admin, you can add, edit, or delete any post.';
}

?>

$role is equal to "subscriber", so the switch statement catches that and echos echo 'You are a subscriber and do not have access to this page.';. You don't want the switch statement to catch anything, so it will run 'default'.

if (!isset($role)) {
    $role = 'AnythingThatIsntListedInTheSwitchStatement';
}

I can't change 

if (!isset($role)) {
    $role = 'subscriber';
}

at the top. I'm not supposed to edit that section, and if I do, it tells me not to edit the code above the switch statement. The instructions say to keep the same default output. "Step 1: Change the second if statement to a switch statement, keeping the current message as the default."

If you are on the first task, use this. It wants you to only add the 'admin' in.

<?php
//Available roles: admin, editor, author, subscriber
if (!isset($role)) {
    $role = 'subscriber';
}

//change to switch statement
switch($role) {
  case "admin":
    echo "As an admin, you can add, edit, or delete any post.";
    break;
  default:
    echo "You do not have access to this page. Please contact your administrator.";
}

If you're on the second task, use this. It wants you to add two additional roles, not them all.

<?php
//Available roles: admin, editor, author, subscriber
if (!isset($role)) {
    $role = 'subscriber';
}

//change to switch statement
switch($role) {
  case "admin":
    echo "As an admin, you can add, edit, or delete any post.";
    break;
  case "editor":
    echo "As an editor, you can add or edit any post, and delete your own posts.";
    break;
  case "author":
    echo "As an author, you can add, edit, or delete your own post.";
    break;
  default:
    echo "You do not have access to this page. Please contact your administrator.";
}

How did you know it only wants us to add 2 additional roles?

Because it says "Add a second check" - so logically it would make sense to have only 2 if anything.
