Tools -> Patron card creator -> Edit layout: A few pairs of radio buttons have duplicate labels: <li> <label for="page_side">Page side: </label> <input type="radio" name="page_side" id="page_side" value="F">Front <input type="radio" name="page_side" id="page_side" value="B" checked="checked">Back </li> It would be better for the "Page side" label to have no "for" attribute and for "Front" and "Back" to be labels.
