removing borders around the slider?

Hi! I’ve been trying to remove any styling above and below my fullwidth sliders but haven’t yet been able to do so completely.

Here’s an example: http://www.soulventures.com

There’s a drop shadow above the slider and a faint line below it. I’ve removed any border styling I could find and have searched this forum for code that works for me but so far nothing has budged it. Any ideas?

Thank you!
