Remove "Permalinkto:" flyer from the homepage

Hello, I am almost done with the update of my website, and i am quite happy with the theme Gradilicious. There is only one thing that I would like to change on the front page (http://www.bunyavirus.org). When the mouse cursor overflies the slides, there is a little box entitled "Permalinkto:" that appears for few seconds. Is that possible to remove this? I find it disgracious. Thanks in advance for helping! PY
