Trying to get a carousel inside a carousel

I'm trying to make a carousel inside a carousel so I can dynamically load larger sections and have everything neatly organized, I am trying to hardcode a carousel inside a carousel for the time being however I am having issues with the third slide not displaying and I cant figure out why does anyone have any suggestions.
