Hi,
Just to be sure, of which "gender" and "description" field are you talking about ?
I don't see any user custom field so I am wondering if it is an HikaShop page or not.
But for the custom fields, you are looking in the right place. You can see the column "front-end" and if you edit a custom field, you can remove it from the front-end (the the user can't access it but you can in the backend).

By the way, do not send me private message, use the "contact us" form instead.
