Logout lands back onto homepage without logging out

I have built zeppelin from master branch and using it.I have enabled basic shiro authentication and able to do login and all normal operations.But when I logout ,It says logout successfull and then redirect back to home page with the same user logged in .I tried deleting cookies and cache but its still the same.
Only case it works is if i open a new window.
