You have created a multipage menu - rather than 3 menus - except your multipage is not correct.
Did you mean to create a multipage?
If so, see this:

The elements of page zero are like a regular menu (your Page_LESN should not be inside a group), and the other pages are grouped as you have them.
If you did not mean to create a multipage (which only work in bluray), make three separate PS files.
