Cascade, by default, will show you a page, folder or file's file name rather than its Display Name or Title. This is the difference between seeing the homepage listed in Cascade as "index" vs. "Home" or "about-us" vs. "About us."
The following instructions will show you how to set the Cascade user preference to show Display Names or Titles, rather than filenames, when available.
1. Click on user menu on the top right.
2. Select Settings.
3. Check the "Show asset's Title or Display Name if available" tab.
4. Submit your changes.
You will now see Display Names or Titles for your pages, folders and files rather than the file names.
