Label name of the core fields

Dear all,
I can't change the name of the label of the Category core filed in the form type article. I would like to replace the name "category" related to the core filed categories displayed on the front end form. I saw that it is possible to change the name of the label of the core field within type -> core fields options. For example, if I replace the name of the label of the Title in the article type with Title2 by going to the front end of the site, the change is correctly displayed.
If I change the label of the category I can't see the change in the front end. In attahced there is a screenshot of the front end as an example.

Thanks for the support

Michele
