Why doesn't my checkout flow work?

Question

I am working on a site that integrates with our company's ordering and payment system. I have a flow I need to create that, after the customer clicks the checkout button, it takes them to a login/register page, then to a place to enter their shipping and billing address, then to a shipping page (which our service provides the shipping costs), then to a payment page. I created a custom flow called 'SRSCheckoutFlow' and here is my code:

class SRSCheckoutFlow extends CheckoutFlowWithPanesBase {

    /**
     * {@inheritdoc}
     */
    public function getSteps() {
      return [
          'login' => [
            'label' => $this->t('Login'),
            'previous_label' => $this->t('Return to cart'),
            'has_order_summary' => FALSE,
          ],
          'order' => [
            'label' => $this->t('Order Information'),
            'previous_label' => $this->t('Return to login'),
            'has_order_summary' => FALSE,
          ],
          'shipping' => [
            'label' => $this->t('Shipping Service'),
            'previous_label' => $this->t('Return to order information'),
            'has_order_summary' => FALSE,
          ],
          'review' => [
            'label' => $this->t('Review'),
            'has_order_summary' => TRUE,
          ],
          'payment' => [
            'label' => $this->t('Payment'),
            'has_order_summary' => TRUE,
          ],
          'payment_processing' => [
            'label' => $this->t('Payment Processing'),
            'has_order_summary' => TRUE,
          ],
        ] + parent::getSteps();
    }

  }

Problems are when I am not logged in, I go to the login/register page as desired but after I register, I get sent to a blank Checkout page. If I am already logged it, I get sent to the shipping page which misses the part where I need the user to add their shipping and billing information.

In Home > Administration > Commerce > Configuration > Checkout flows, I have all the steps created in the SRSCheckoutFlow and I added the following to each step

Login

• Login or continue as guest

Order Information

• Shipping information
• Contact information

Shipping Service

• Shipping Services (which is custom and showing correctly)

Review

• Review

Payment

• Payment information

Am I missing something in the flow that jumps over the Shipping information and Contact information sections?
