Memberlist Sorting works only for admin

[Angelus]

HI. I have a strange problem. If a normal user sorts ascendending or descending for posts the sorting is wrong see picture:

But when I as admin do the same it works:

I run an integra 1.4.0 with phpbb 2.0.19.

There are also other strange things. If I chosse sorting after reg date as user there are users without regdate and/or Online status:

[flash=,:1kyct2sg]http://www.world-of-miniatures.de/bilder/integra/memberlist3_user.jpg[/flash:1kyct2sg]

I see everything correct:

Anyone any idea how to fix that?
