Sandbox console is empty, but shouldn't be

My API is returning an error saying that a customer’s email already exists, but the Sandbox console doesn’t show any customers.

Whats up with that?

@drewbaker, Strange. Does the email address exist when you call the API to retrieve a list of your Customers? Have you attempted to logout and log back in to the White Label Sandbox Console with the account you used to create this Customer?
