Freshy 2 problem

I have the theme freshy 2 and the plugin wp reciprocal links. the plugin creates a form that handles link exchange requests. My problem is that there is a small box that covers an area of the form. this only appears using the freshy 2 theme. I think the problem is javascript conflict because there isnt any reason in the html code (which is very simple without anything complicated) why this box should appear. The plugin uses some files from Jquery UI

This is the problem

And this is how it should look like
