Slider buttons not located properly, breaks menu

Hi Folks!

I apologize in advance, I am very green to WordPress. I have some basic HTML/Dreamweaver experience.. but anyhow:

I am making a new website for my small company. I purchased a theme and somehow along the way I broke my slider. Traditionally it has a left and right button faded over the image in the bottom left corner.

Somehow they have floated to the left and are now in the menu section of the website… which is disabling that menu all together.

To see what I am talking about this is where my preview currently is – https://www.rcsearles.com/wordpress/

Any ideas on how to fix this? I have tried going through the coding and I still can’t figure out where the issue is coming from. I even tried re-uploading the style.css from the original download and that didn’t fix the issue. I also tried other image sizes thinking that the width was expanding the invisible part of the window over the buttons… I don’t know…

Help!
