Galleries Box missing from Menus page

Can I ask how this problem is solved?
My very first administrator account can see Galleries (post types) allowed to add to the menu. No other administrator accounts can see the Galleries box to be able to add galleries to the menus.
How can I allow all the administrators to add galleries to menus?

It can’t be a matter of who created a gallery. There is a list of galleries created by each administrator. But all but the very first one can not see the Galleries box on Menus page. (there are Pages, Links and Categories only)
