Portal Alias Disappears after Log Out

Currently, i am in the middle of a process and i would like to mention about the problem that happened while i was testing the application.

Here is the scenario.

Install a DotNetNuke 4.8.2,

Upgrade it to DotNetNuke 4.8.4

Then create a child portal and use an alias like childportal

After creating child portal, login to that portal as childportal admin account and create some pages with content.

Now try to logout, and login with host account, try to logout and login with childportal admin account this time.

If you follow the URL's in address bar, you will notice that while logging in or loggin out, childportal alias not being displayed.

I will present the problem via images or a video later.
