How to restore Portal defalult Categories?

Question

After installing Portal for ArcGIS 10.6.1 and starting with some test  I chosed the "ISO Category  classification".

After that I can only manage and change the single categories voceis but I can't :

* restore the iniztial status (NO categories)
* go back and choose anotehr categories template (example Inspire categories or custom)

Either in My organization settings i have only the possibility to manage the single voices added.

How can I restore the initial condition?

thank you

Auto-Solved:

you have to delete all the categories voices.

When  everything i cleaned, ,Portal will present you  the original category settings page where you can choes from the 3 different templates (ISO, ISNPIRE, CUSTOM).
