Ok, now I see. It looks like it’s all coming from the custom CSS code that you added to the bottom of the style.css file. Since there’s already column class code added inside the theme by default, you can go ahead and remove it. Once you remove the code from the bottom then it should start functioning normally again like the demo.

.five-sixths,
.four-sixths,
.one-fourth,
.one-half,
.one-sixth,
.one-third,
.three-fourths,
.three-sixths,
.two-fourths,
.two-sixths,
.two-thirds {
float: left;
margin-left: 2.564102564102564%;
}
