I would suggest checking the permissions of the file, you may have to give yourself write permission to change the title.
Also, if this doesn't resolve it, remake the clips, and name them all the title you want, and the 2nd will be NameYouWant2, 3rd will be NameYouWant3 and so on, and then since it uses the name of the first clip, it will display the name you want.
Hope this helps,
Brian
