How to delete the component Nameinformatio1in the Name style for several countries?

Hi everyone!

We have configured Person Name Style for 22 countries using the component Nameinformation1, then employees were loaded through HDL successfully. We noticed that employees from USA have autopopulated the field nameinformation1 with the information loaded in first name and last name. This has an impact on the Name Format (Global Type) because the employee´s name looks duplicated.

We want to NOT use anymore the component nameinfromation1 and we expect to use the component Previous Last Name. Unfortunately,  it seems we cannot delete that component because the button is unable to. Can you tell me how can I change, edit or delete the component nameinformation1 from Person Name Style ?
