nevermind has nothing to do with hyphens. Codename can be anything. What is happening is you need to create the child page, then go back and "edit" the child page and save it again before the child page begins working correctly.
I think maybe you are expecting it to redirect to the page after creating it, but the convention is that inline links always lead you back to where you were when you clicked them (i.e. the parent page).
This way you can add a lot of child pages in bulk.
Odd. It's a problem on lovinity.org and that's not what I'm expecting.
What is happening is I'll create the child page. If I try to then go to the child page either by clicking it from the parent page or by going to it directly by URL, it takes me to the parent page and not the child page I want. It isn't until I then go to the edit screen for that child page and click save that the page then works properly.
