5. Add a new navigation menu named test menu and choose welcome page and test page.
6. Go to default page and change navigation menu to use test menu.
7. Publish to live.

Expected result:
There are welcome page and test page in navigation menu.

Actual result:
There is only test page in navigation menu.
