Changing the name of a country, every nation has their tag as their name now

Not sure what is going on here. This only happened when I changed the name in the localization .yml file. Been looking at other mods for an example and I'm doing exactly the same thing, but every time this happens.

Any idea what I'm doing wrong? Editing the .yml files with wordpad.

Solved my own issue: I think it was the editor. Used Notepad++ after restarting it all and it worked.
