How to change type of production?

Looking for solution to a current situation and I am not sure how to proceed with this one.  A title has been established already, however when it was first set-up it was submitted as a documentary.  It is a documentary - one made for television and has 13 episodes.  Currently I cannot add episodes to the title.  I am assuming because of the way it was set-up.  Is there any solution to this?  Should I ask to have the title deleted and start over? Any insight into this would be greatly appreciated.
