User Name in Homepage

Content (please ensure you mask any confidential information):

Hi Experts,

There's a question around the user name's format on the homepage, that currently in our implementation, the user name is showing in the format of:
[Last Name][First Name]
Is there a way to configure it into:
[First Name] [Last Name]
?

Please refer to below screenshot:

I notice that in Oracle webinar's demo, the demo site is having the user name's format as we wanted:
[First Name] [Last Name]

May I ask how to achieve that please?

Thank you very much.
