Sage ESS Menu limit?

Does ESS have a maximum number of menu item options under a specific Menu heading, for example, Benefits.  For example, a client has 18 currently, they added a new one and the whole page blew up.  She removed and added the menu item to a new page and the existing came back and the item is listed as expected under the other page, which has far less menu items.
