Look what I got in email.
I just ran the api
It reports correctly as Ordoñez

So it must be something in the UBB cp script that is misinterpreting it.
Have you tried the age old fix all "clear cache" in UBB?
Notice how it's rendered? So, this is clearly not a UBB problem. It's something on the server that is incorrectly configured.
I'm sorry for taking up so much time on an issue that's unrelated to UBB.
