translate strings for menus are not created when using create page

I created new page (create content->page) and typed in "Menu settings" some menu item.
Then I open "Localizer strings translation" & try to search newly created menu item... it's not found...

I solved it like this:
open edit window for this item & press "submit"

after that translate string was created and appeared at "Localizer strings translation"

sorry for my poor english...
