issue with CoursePro and Woocommerce/

I have did the settings related to integration between coursepro and Woo but the payment options are not coming to the user when he join the course
when I went to setting I find that the last step in course setting still marked as not completed
I do not know what should I do to finalize this
the product is created for the course in Woo and I did the payment setting on it
even the direction to course page is ok
but payment is not coming to the user, only empty pop up
Please Advice
