Enfold Advertising Area Widget: How to remove "Advertise Here" text?

Hi,

I’ve been trying to place a button that, when clicked, goes to another website. It’s to appear everywhere on the website (right sidebar). At first, I tried doing this by utilizing the Layer Slider, but it looked correct only on the home page. I tried using the Enfold Advertising Area Widget, and it works perfectly…except beside the graphic appears the text, “Advertise here” and it’s clickable. It goes to another webpage on our site (not sure why it goes to this particular page as I did not specify where it should go).

I’d like to delete the text altogether. Is this possible? Thank you.
