Change Titles - Need Help Please!

Our series "Betrayal" is currently listen under the season 1 title... There are currently 3 seasons and we need the main title to only be "Betrayal" I've tried to change the series title and it already tells me that its "Betrayal." I also need to change this from a TV Miniseries to a TV series ans I'm having issues doing that as well. Any help is appreciated. Thanks!
