All images from Instagram not showing on slider

Website using the plugin: http://www.christmascrosshunt.com
WordPress Version : 4.3.1
Instagram Slider Version : 1.3.0
Theme Name : Genesis Dynamik
My Problem : I am using the #christmascrosshunt to get pictures from Instagram, but not all the pictures (they are all recent) with that # are showing for some reason. Do you know why?
