Sidebar problem

Hi, I just installed this plugin and works okay except for 1 big problem.

I find that whenever I have a custom sidebar (made with this plugin).
The content in the sidebar is duplicated.

If I put recent posts in a sidebar it shows up twice and I find really annoying. I looked everywhere in the php to find the problem but I was unable to so maybe someone can help me out.

Thank you very much.
