menu sub item

hi one and all when hovering over my members tab on main nav
sub tab has seemed to of dissapered, now in my menus setting
i have register underneath members? now could anyone elaborate
as to why registration isn’t showing up? is it maybe a wordpress error
or is it something to do with permalinks setting?

or if its easier for my members to register how do i create a register and login link just like these forums has
