The setting "Sessions to display on course page" does not appear to work. Regardless of the number of sessions selected or the theme used nothing no sessions appear on the course main page.
Steps to recreate issue.
1. Add F2F activity to existing course.
2. Set "sessions to display on course page" to desired setting (I started at 2 and went up from there in my testing).
3. Create multiple sessions (I created 15 in my testing).
3. Navigate to course main page and note that no sessions appear.
4. Go back to F2F settings and change "sessions to display on course page" to another value.
5. Go back to course main page and note that no sessions appear.
