Magento EE – Why DOB and Gender Configuration are Disabled

I was looking for a way to enable DOB and Gender and well I saw that there is a configuration under System → Configuration → Customers → Cusotmers Configuration → Name and Address Options and there should be two dropdowns with the configuration for DOB and Gender. The thing I saw is that in app/code/core/Enterprise/Customer/etc/system.xml is that they are not configurable through any of the three scopes (Default, Website and Store), the code here:
