Enroll “Data Science specialization” and could not start education

Hi there! I recently enrolled on specialization (https://www.coursera.org/specializations/jhudatascience), paid for it and now I can’t start education. I fill up my profile, but specialization doesn’t appear in my enrollments.  Then I go to specialization page (see link above) and coursera offers me pay again to enroll. What am I doing wrong?
