Shopify Section Store Image Gallery mobile issues

[StGeorgeStuff]

Im using the section store App to create image galleries for artwork on my site, but I cant figure out how to fix an issue displaying on mobile. Each gallery section is 1 large image and 6 small ones, and they work fine on desktop, but when loading them on mobile it doesnt show the large image or the last 2 of the 6 small, effectively only displaying half of my gallery to mobile users.  I cant seem to find anybody else having this issue, and cant find anywhere in the settings that could be causing it.

Thanks
