Wanted to change title type from Movie to Series, but doesnt work

Hi tatjana1984- Thank you for posting the submission reference and title link! Further investigating, the reason why it did not let you submit this correction is because there is already a title for this series live on the site with the correct title type as "TV series." Therefore, in this case, this duplicated page has been merged to this title: https://www.imdb.com/title/tt27763255/ The changes are in-progress but will be live on the site shortly. Cheers!
