Hello Ryan Deal,
We developed the theme slider section with the background image which suits on every devices but in case of small devices, the image is not cropped properly. This reduces the burden for the users to make the actual image for the slider items. If you can able to add the actual image size as the theme takes, that is good too.
We will consult with the developer team and address that issues how we can solve it.
Thank you for your patience.
Regards
