WordPress 3.5.1 missing parent in permalink for child page

While creating a page you need to select parent page from page attributes column in the right hand side

Under Settings-> Permalink tab

create custom structure like - /%postname%/

FYI - Tested at my end and URL created like - http://localhost/wordpress/sample-page/page-2/

I'm currently using Hueman Theme but I'm also experiencing like yogidevbearhad. I want to use URL format like http:// example.com/parent/child/. I have checked all the slugs, page names, post names, and no duplication was made. Have permanently deleted all trash. I have set the permalink settings to http:// example.com/%postname%/. I have the child page's page attribute set under its parent page. I also have updated Menu Structure of my child page put under the parent page as sub item. When I view my child page the permalink is changed to http:// example.com/parent/child-2/.

How come it changed from "/child/" to"/child-2/"?

I went back to child page's page attribute and set it back to "no parent".The pages URL then changed to http:// example.com/parent/ for the parent and http:// example.com/child/ for the child but in the menu the child tab is located under the parent tab.
