Hi Bernadette,
As Eddie said you can only edit a last name if you re a profiel manager.
This profile was created in June this year. So the profile manager might be active and still around. Please send a (kind) private message to the profile manager requesting her/him to add you as manager. Declare why you think the LNAB should be different by showing links to real documents. Hope this is helping you.
Kind regards from The Netherlands,
A
