Influence Home Slider size

Hello,

Great themes and thank you for creating them! My home slider is very narrow on the page. http://impactsportsvideos.com/

Also following the instructions here https://siteorigin.com/influence-documentation/theme-settings/home-page/ I cannot see where there is a dropdown to choose the slider. Right now there is only the option to apply a short code or “Edit Wdget” button. I applied this short code to it. [home_slider_widget] and no difference. “Menu Overlaps Slider” is not checked. Slider margin is checked. I am using Version: 1.2.1

The background image is 2400 × 1601 and the foreground image is 474 × 150. Do you have any ideas what could be causing this?

Thanks for any help.
