Using a template gives the same name to all pages created based on the template. You can rename the page in 'pages menu' but the page name still remains same in the 'component navigation bar' or even in the options available while creating an 'event'. This makes it very difficult to choose the right page when you want to navigate to a page depending on a button click or something similar.
Creating a duplicate of such a page gives an opportunity to change the page name in all places but whenever you update the template, all page names are changed to a same name again.
Really problematic issue.
