I temporary fix that issue, apparently is because of the description items, some of them have 4 paragraphs and other 3 or 2 so it brake down the columns, dunno if the creators of cardinal will have a better fix for this but as for now, you can do this:
.products .product .product-details {
text-align: center;
max-height: 60px !important;
}
That fix my isssue, hope it fix yours, as I said I tweak css to achieve this, hope cardinal creators offer a better fix.
