I’m trying to remove the title of a page node on Drupal. I have this page:

And I want it to look like this:

As you can see, I want the title to be removed, but only for taxonomy terms. If I try to erase it using CSS, I erase al page-titles, so I wanted to use this module, that allows administrators to auto-generate node titles and hide it.
I go to structure -> type content -> my type content, and edit it. I activate the module, and I want to auto-generate titles depending on the node category. I think it should look like this, but it doesn’t work…

Any ideas why?
EDIT: Sorry, I forgot to say: yes, when I activate the module, use it, and select the category as the auto-generated title, it works. But it doesn’t hide the title…
It also launches this mistake:

Sorry guys, it was as easy as hide title tag on “manage presentation”…
You are all right on your responses, but they were not exactly what I needed… thanks!
