Problems with Pro Sites 3.1

Hello!

Since the update of the plugin it is not longer comfortable to look for Blogs within the "Pro Sites Management", especially as I always get an error message.

It is looking for my Blogs at this URL:
http://wpms.local/wp-admin/network/sites.php?s=blogname&submit=Search+Sites+%C2%BB

It only works the I insert into this URL the url of my Website manually.

It would be really good to correct this failure, other wise the function is useless.
