Sugar sort by last name, instead of first name, when sorting Leads/Contacts by Name in List view

Hi,

Problem: When in the Contacts/Leads module (list view) and you sort the list by the "Name" column, Sugar sort by last name instead of the first name.
It has been like this ever since we upgraded our Sugar system from 6.x to 7.x., all users affected, and I cannot find were I can change this.

First I thought this was controlled by the "Name display format" setting in the user profile, but no.

Please see the screenshot below, I have sorted my Leads by the Name column. How can I make sugar sorting the leads by first name instead of last name?

Is it the same in your systems?
