Time of Your Life is an American television drama series starring Jennifer Love Hewitt that aired for one season on Fox. A spin-off of "Party of Five", the series followed Sarah Reeves Merrin as she moved to New York City to learn more about her biological parents. Co-stars included Jennifer Garner, Pauley Perrette and Gina Ravera.
This wasn't a series because it only aired one season.
Just because it aired one season doesn't mean that it wasn't a series because other seasons could have been pre-recorded.  The system thinks it's wrong because it has no knowledge of the recordings.
