How to modify already imputed Custom Registration Fields

[Cixi]

Hello.
I went to:
Configuration
Features and Options
Profile Fields

And I added 3 more fields.

I decide to be mandatory.
But most of the people does fill them with not true parameters.
I'd like to be able to modify them like I do with other Profiles parameters to enter the correct one.
I can't even see mine!
Is there any way to show them to the ADMIN only and modify them without enter them directly from the Dbase mySQL?

I found later that someone has already registerd that I have an option to edit them and to show only to user and admin but after enable that feature I still can't see the field into
Profile
Modify Profile
Account Settings

It only show one Custom Field instead of 3!

Thank You

I found the solution
Sorry to post this.
I did not see the option dropdown menu.

Then I went to:
Admin
Configuration
Features and Options
Profile Fields
then Custom Profile Fields
then Modify
then I changed the "Profile Section:" from None to Account Settings.

Thank You all.
