Best regards, Paul.
The CSS code worked perfectly.
However, when entering an article in the Cundinamarca category you still see the text "featured"

First of all, I understand and appreciate that they implement new functions, this makes Helix Ultimate definitely the best Joomla FrameWork and it shows by far.
Just a respectful recommendation of course, always keep in mind that these implementations are optional as much as possible or that at least we have the possibility of enabling it or not, and it is not something that we must accept without the possibility of changing it unless they provide us with solutions such as the one kindly indicated by you.
The "featured" function that it indicates could easily go within the "Blog" options and with a simple button decide whether to use it or not just as happens with other options, keep this in mind for future functions.
For the rest, thank you very much for your great help.
