Slideshow Previous and Next Filters

I have created a little gallery slideshow on my homepage. There is a huge filtered section when you hover over the Previous and Next arrows. How can I remove that? I tried my own CSS with no luck.

I’ve included a screen shot so that you know what I’m talking about.

The website is http://www.lelandcc.com/wp, but it’s password protected and I can give you the login information on a private reply.

Thanks,
Diane
