Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello

I've been playing several days and the interface is not showing my own name and other players/mobs/names etc.

It only shows ... (3 dots). It worked 1 day when i adjusted the options but now it's not working anymore although it's marked in the options.

Can somebody help me so i can see my own name and the target name?

You've screwed with the UI scale somehow. The text is either so big or so small you can't see it in the nameplates.

Is there a way to change it or to fix it?
