Change OS front page

Hi,

I have been used a tutorial made by rolando.isidoro found here (groups) to change my front page. Like this:

1. Access the Context settings area using this URL http://your-openscholar-domain.com/admin/build/context/list
2. Locate the sitewide_front context under the openscholar > section namespace and click the Override link;
3. In this form click on the Edit tab located on the top left below the Context title;
4. From here you can disable the blocks that are active from default, like OpenScholar: Video info or OpenScholar: Mission Statement, and add your own, like you would do on any Drupal powered website;

Instead of override, I have been cloned the openscholar-section-sitewide_front (attach 1) and made the changes I need. I labeled it "bemvindo1" (attach 2). I go to /admin/settings/site-information and set Default front page as bemvindo1 (attach 3). However, when I push save button, I got the error message: The path 'bemvindo1' is either invalid or you do not have access to it.

But, I can access the bemvind1 page by browser. Please, see the attach 4.

Please, what was missing? Am I wrong? Thank you very much!
