Images disappearing when using Boxes

[jordana_che 0]

Hi, I just started working with Platformpro; using the child theme. I am experimenting with boxes and I am losing the image from the last box (only using two so far). Here is the page I'm working with: http://jordanadance.com/boxes. The past posts on this subject aren't helping. Loving using this theme although I still have tons to grasp. Thanks for your help.
