I've stated on here before that GBPs names can become different between languages. Normally, you can only guarantee to change the language that you are currently editing in the NMX dashboard. If you wish to correct the other languages, you must make manual edits.
Now the strange thing is, the name displayed for editing in the NMX dashboard is always the name in the language that was being used when the profile was created. And that rule applies: in such a situation, it's the name in the desired default language which cannot be edited at all in the NMX dashboard!
This can be confusing because sometimes Google just... shows a name that is different as a bug, but this is NOT that, it's literally just showing the name in the other language for shits and giggles! So technically you're not even editing the same name that is being displayed in the panel preview to the right of the screen.
