Directory Menu Option not honouring “only logged in”

Hi,
On one of my churches’ apps, in the menu settings, the Directory is set to show, and to show only to logged in members, but it is showing to everyone.

In one sense, it’s not a major problem because users have to log in to use it, but I’d rather it NOT be shown on the “show to all” page.

If I uncheck both boxes, it disappears. (Correctly)
If I uncheck the “show” box but leave the “show only to logged in” it hides on the general page and shows to logged in. (This will suffice for a work-around, but it’s not how I think the menu is supposed to work.)
If I check both boxes, it shows all the time.

Can you have a look to see what’s amiss, please?
