The likely cause for this is because the Manager Role does not have the Preview School Form Task enabled. To enable the Task navigate to:
  1. Core > User/Access > Profile > Manage Roles > Search for the Role
  2. Click Into the Role
  3. Click Tasks
  4. Click CTRL + F or Command + F if on a Mac
  5. Search for Preview
  6. Click Edit next to the "onProduct" School Form Preview (for example if you are enabling this for a onCampus Manager Role ie: Athletic Group Manager, it would say onCampus School Form Preview)
  7. Mark the box for Active
  8. Click Save & Exit
  9. Logout and log back in to see the updated Role changes
