Page Title was changed to Home for User/Register, User/Login and User/Password

Hi
I don't know if there was a conflict with Drupal Core after I installed and enabled the following modules, the page title for user/register, user/login and user/password was changed to Home instead of User Account. Now, even I disabled and further uninstalled them, Home still appears as the page title for user/register, user/login and user/password. How to trace the changes of the page title variable ? Tks

2.) Entity Translation
