Reporting an issue wherein if you set 'Booking in groups' to an option other than 'no', while the grade for scheduler is hidden in the gradebook, the student can see the grade in the activity regardless of its setting in gradebook.

Steps to replicate:

1. Go to a course or create a new one
   1. Ensure that there is a teacher and at least one student enrolled in the course
2. Create a scheduler activity
   1. Give the activity a name
   2. Leave all settings as default except
      1. Booking in groups - Change to an option other than 'no'
      2. Under grade, set type to point
      3. Set a grade to pass if you wish.
   3. Save changes
   4. Go to the course gradebook setup
      1. And hide the scheduler grade item
   5. Go to the scheduler activity
   6. Create a single slot
   7. Allocate a test student, mark as seen and grade them, saving changes.
   8. Log in as the test student
   9. Go to the scheduler activity

Observed: Grade is visible even though it is hidden in the gradebook

Expected: Grade should not be visible if hidden in gradebook.

Additional notes: This works fine when the setting 'Booking in groups' is set to 'no'.
