If I Shouldn’t Use Zaire, Why Is It An Option?

I’m trying to apply for a job at the UN. I love being Zimbabwean as I can just scroll to the bottom to find my country. This time, I noticed something strage.

If I’m not supposed to use the option, why is it still there? Y’all control the website so surley you can remove it. Maybe people still think it’s called Zaire? Even still, can’t they make the association on the backend instead of asking you not to pick it?

And if you’d want to know, Taiwan is listed as a province of China and Hong Kong and Macau are special administrative regions of China. Somehow Taiwan isn’t under China like the others.
