It shouldn't have let you create a new page over an existing one. In such cases, it should have you edit the current version. As such, I am not sure how you would "select Main". Could you please provide a link to the page so that we can see what happened? You should be able to change the title by just moving the page. However, if you accidentally overwrote an existing page, you will want to make sure to restore the overwritten version.
