Left slider arrow is backwards

I added the Genesis Responsive Slider to my home page, but the left arrow is backwards and out of frame. I followed the installation and setup directions carefully given to me by my theme developer. I’m not very tech savvy, so I didn’t venture from her directions at all. I contacted her about the issues, and she checked all the code and couldn’t identify the problem.

The slider is also overlapping with the Genesis Featured Page widgets below it. I don’t know if that’s an issue we can resolve here or if I should ask about that elsewhere.

Thank you so much in advance!
