Settings will NOT "stick". Is there a fix?

Hello all!
I have just installed the sitewide privacy options for Wordpress Multisite plugin.
It is in my plugin folder, network activated on a fresh multisite using Wordpress 3.1.3.
The only setting that it will hold in the Default Setting is: allow all visitors to all blogs
I tried to set it to block search engines from all blogs, but allow... and it won't "stick".

Can someone please help?
Thank you
