Multisite (new site) has wrong "siteurl"

I have created a new site on my Multisite install.

The link -- (http://cls-manager.com/new-site/) -- leads to the new site.

However, when the "New Site" text name is clicked, it goes to the Multisite's main website -- (http://cls-manager.com)

When I go to edit the New Site, I find that the "Site Address (URL)" is correct -- (http://cls-manager.com/new-site/).

But when I select the "Settings" tab, I find that both the "Siteurl" and "Home" are not correct -- (http://cls-manager.com).

When I make the correction and click save, the corrected information disappears and is replaced again with the incorrect information.

How can I fix this problem?
