Slider Malfunction

Hello! First of all, I LOVE LOVE LOVE this theme!! However, I’m having an issue with the slider. I set it up through the customization options and on the home page (the only place I have it enabled), the first slide shows up with the correct attributes, but the following three do not. The second one doesn’t show up at all. The third one shows up, but without text – though when I hover over the place where the text should be, my cursor does think there’s something there. The fourth one shows no image nor any text, just a blue box.

I tried to get around this by installing different slider plugins, but they all have a crappy white margin around them and unfortunately, I’m not skilled enough to try to edit the code.

Please help. Thanks so much! ??
