You might check your slider settings on the Genesis tab, to match your images.
I tried the Genesis slider and did not like it. I would recommend you use the Siloquoy Slider. You can buy the basic for $19 (please support developers) or use the free version: https://wordpress.org/plugins/soliloquy-lite/ if you want to see how it works.
I use it on all my websites. You can make as many sliders as you want on as many pages as you want. You can set the dimensions, the speed, and the look (limited in the free one).
All you add is a short code [siloquoy3452]
wherever in the widget or on a page, and it works.
You can also use basic code to make it center, etc.
I use it for the basic slider, and slider wide, and for mini slide shows on numerous pages. Check out this site to see it in operation: http://www.unitedsportsmen.com. It is FAST too.
