Single Name Field splits into firstname, middlename, lastname in database

Hi,
I set in CB Configuration:
Name style: Single Name Field
Name format: Name Only

With this configuration, user manager shows only a 'name' field, but when I save a new record the single name is split in three different fields into database (firstname, middlename, lastname). I don't understand this behaviour: I need a single name (my db is for organizations) stored in a single field and not split in three. How can I have a single 'name' field in file manager AND in database?

Thank you

Adjust "Name Style" as needed in CB > Configuration > General.

Thanks, but it's not helping, I already did as stated in my first post.
I need single name field, and this is how I set in Cofiguration--> General
But when I check database through phpmyadmin the single name is split into three fields.

Example:
In user manager, in Name field, I set "Joomla Community Builder"
What I see in database, though, is:
firstname --> Joomla
middlename --> Community
lastname --> Builder

I was expecting to have everything in a single field, why is split in three?
Thanks

It's always going to split the name for storage in _comprofiler. It's already stored as a single name column in _users, there's no reason for CB to duplicate that in _comprofiler.
