Enrollment button missing

Hi, I’m having trouble with creating an enrollment button in my course. I created a course and used the shortcode [namaste-enroll] to display an enrollment button but when I open the page publicly (and not logged-in) there is ‘You can enroll in this course from your student dashboard. You need to be logged in. ‘ instead of the ,Click to enroll’ button.

Can you tell me what I’m doing wrong?

Thank you.
