This is a bit out there, and I tried to search but couldnt find anything.
Before creating a service ticket I was hoping to see if anyone else has seen this issue.
I just installed OBIEE 12c and went into
Enterprise Manager -> Application Roles -> Edit
Here I click on [Add]

I select the user [rosem] with display name Michael A Rose

I click OK and it brings me back to the application role main screen.
I go back into the exact same group and noticed that their display name has now changed to "Rose Mohi"

The display name is correct, but some how it looks like the display name is not being loaded correctly.
Has anyone ever seen this?
