First name and last name sql

After adding this sql queries and went to ---->admin panel > settings > advanced settings > profiles > Member Display-Name

I got this : _sys_member_info_first_name_last_name and also got this sys_member_info_last_name_firs_name and got this one here as well _sys_member_info_first_name

How to resolve this please ?

Thank you

Have you add the translations in the install/langs/lang-en.php
