This is a broken `menu-item`: the `:filter` above is not treated as
a keyword argument but as "the command".

You should use something like:

    (define-key global-map (kbd "C-c C-l r X")
      `(menu-item "2" ,(lambda () (interactive) (message "Called"))
                  :filter ,(lambda (cmd) cmd)))

[ of course, I assume you'll use a more interesting filter than the
  identity function.  ]
