Question Member Search from Memberlist not working ?

I tried out the memberlist search function but it does not give me any results back.

Here is my config:

I can confirm that the User Search does nothing

Updated Joomla and Kunena - User search in memberlist is still disfunction...

Still no idea why member list search and sort function is not working ?
I´m using the "EVOLUTION SLATE - FREE Kunena 1.6 template" 1.6.3 Template.

When I switch to "Kunena 1.6.3 Example Template", the member list search does not work, too but the sort function is working here.
