Help With Registration Fields, Please

Some of the fields shown on the profile by default are not showing on the registration form when a new account is created.

As shown in the screenshot attached, the fields beside the profile are: Age, Country, City, Distance.

The registration form only asks for Username, Email, Password.

I tried added Country as a custom field. It showed up on the registration form, but did not populate the field on the profile.

How do I populate the “Country”, “City” fields on the profile beside the photo?

How do I remove “Distance” field? I don’t understand why that field on a dating profile.
