Cannot see fields on the checkout page (Drupal commerce)

I am able to get Behat to fill in information on normal Forms in Drupal.
However when it comes to the checkout page when buying an item on a Drupal commerce installation. http://domain.name/checkout/34885
Behat is unable to see the fields on that page.

Below is an snippet of the scenario when the test fails:
And I fill in "123 Address Street" for "edit-field-user-address-und-0-thoroughfare"
And I click "Continue to next step"

The error message as follows:

And I click "Continue to next step" # Drupal\DrupalExtension\Context\MinkContext::assertClick()
Link with id|title|alt|text "Continue to next step" not found. (Behat\Mink\Exception\ElementNotFoundException)

Weirdly the below works on this page:

And I fill in the following:
| Telephone | 0123456789 |
