Since the one that doesn't work doesn't have any value associated with
it, it won't be submitted as a form element (which is why you are not
seeing it as a key in the form data). In other words, it's being
rendered incorrectly. So it's working fine, given what is being
rendered.

The details are hidden in the line you have written as "looping over the
fields in a nice way".
Construct a small self-contained example of a form and formset class and
show exactly how you are attempting to display the form fields and we
might have some chance of spotting the problem. Work hard on removing
every detail that isn't necessary -- removing form elements and formset
details as much as possible until the error disappears. Ideally, you'll
end up with a form with only one field and it will become apparent what
the problem is.
