Title tag always shows the token selected + "Document without title"

Hi!
I´m using Drupal 6 and the moduel Page title 2.7. My issue is that always the titles of my urls are the token I have choosen for that content type + "Document without title"
I can´t understand the reason. I have checked the admin/settings/page-title for my content types I have the token [title] but always is printed the token plus that expression. I have cheked the configuration for the cotent type I have the samen token, nothing more.

Please any help?

Thank you!
