displays title of sticky post on bbpress widget

Hello,

After I install the plugin unexpected thing was happen. When I set up one post as sticky, the title of this post display on first position of box with bbpress widget recent replies topics, in sidebar.

Also the second strange thing is that it displays only on category of this post.

Could you help me with this?

Thanks in advance
Daniel
