Doubled posts

Hello,

First of all Thank You! The plugin really provided a very good option for ordering my posts.

But then a problem appeared. When I use this plugin to order my posts, they are being doubled. An example can be seen here: http://helsus.org/category/helsus-dalibnieki/sevis-izzinas-darzs/
For example, the posts (people’s profile) “Baiba Gerharde” and “Biedrība “Mediācijas padome”” are being doubled.

Do You have any advice?

Thank You!
