There is a hidden form associated with this cc-number that makes the section valid, since this hidden form contains cc-exp-date or cc-name or the like. Since the other visible fields on the page are separated by iframes/hidden forms, we only autofill the cc-number and the hidden fields next to it. There might be another website side error that prevents the values from being copied back to the visible fields, but I don't recall off the top of my head.
