I believe that is a serialised array and you can’t just change the text as it will break the array.
If you want to send me the whole data in that row and tell me what you want cganged then I can do that for you and send it back

yes, didnt want you to change it because as Andy says, its a serialized array… just wanted you to find it and then report it so we could help…
and does sound like wishlist picked name, but oddly we have code to change it in the stats when its changed in wp… bit of kicker is that you are not letting users change, but should do same for admin changed names…
and of course, why I am curious if it was one off or every new user…
You guys are fantastic!
But I want to give you a great piece of news!
In Forum–>Profile Option I changed the function Display Name Format from WP Login to WP Display Name.
Guess what? It worked!
Now the name shows up perfectly!
I will keep an eye and let you know in case something goes wrong.
Thank you so much to you both! 
new piece of info there… as I said, the newest member stats get changed when the display name is changed… once a user is created, they cannot change the login name, so it would never change…
