Hi!
While it is hard to tell only by the look on the front-end, I can see the place, event, wpuf_input and the page custom post types are selected for searching.
Those are results from the wpuf_input custom post type, as their URL suggests. On the General Options -> Sources panel, make sure to check if that custom post type is selected, and deselect it. It might have a different name, as wpuf_input is only the slug I see on the front-end.
