Please create the page first, the menu table stores only the page_id and the alternate title for the menu item.
If you have already created the page, please check if the provided page tag you want add to the menu is correct. Since 6.0.6 all tags are accent and case-sensitive.

##INDEX##
##Index##
##index##

Update:
And if the page does not resides in root, the tag must contain the cluster. 
##Cluster/Index##
