BuddyPress.org

I have a theme that only displays @username at the user profile page at cover page area
I wanted it to have it,display the Users full name followed by the @username
presently this is how it looks as using an example demo format

As I wanted to achieve a display result of something like this:
https://postimg.org/image/ym0tuaoy3/
OR
a result where the full name is displayed above the cover page

I had tried many ways but could not.
The closest code I found was a way to remove and hide the @name

Although am not quite the dev individual I do wish I would find people who know how to go around this features and solve the problem .
I do appreciate every one who has read this post, and hope to hear from you soon
Thank you.
