this typically happens when other formats are converted into UPF.
Very often the information on the principal quantum number is missing
in the original format, so the (software) converter puts a *. It is the
task of the (human) converter to edit the file and put the correct value
of N (which, by the way, is not used in any actual calculation, but may
be shown in the output of some types of calculations).
