It is no particular field. Just a field I have added to a CF7 form. When you take a look at the function I mentioned than you will see, that this if-condition compares a numeric index with an string. This causes the first element in the array of the form field to be skipped.
When you change this to
if ($v->name != ‘submit_ip’) {
everything works fine and the Advanced CF7 DB listing contains all field of the form.
