Zillashortcode: Text in toggle box gets overflows/cuts off

I used the Zillashortcodes app to create toggled information on one of my pages. However, when it expands the box doesn’t get big enough and the text overflows out of the box and then gets cut off by the next box. Is there anyway to make the height auto adjust?

When I use Chrome’s source editor, there’s a style called element.style that defines the height. If I delete the “height” (which is populated somehow) it will automatically increase the length of the box and it’ll be fine, but I can’t figure out how to change it in the actual code. It doesn’t say what style sheet it is in and I don’t see it in the plugin’s css. Any ideas?
