"Display Tickets from private departments in the Help Center" and "Show departments list page on choosing to submit a ticket" don't works in my environment Zoho One

Hello, 
I've set up a help center with a public department and several private ones.

In the help center settings, I have validated the following 2 options:
- Display Tickets from private departments in the Help Center
- Show departments list page on choosing to submit a ticket

However, only the public department and its tickets are visible in the help center. The private departments do not appear.

How can I make them appear?
