Padding and other errors

Hi there,

I hope someone might be able to assist. I installed Smart Slider on my site and created three simple slides with links to some of my pages. Problem is that the padding goes all weird at the top of the buttons when I publish, and a random smaller button with no text is generated right underneath it. Is this a conflict error? Should I install a different slider? Any help would be appreciated.
