I was going to upgrade my ProZ.com membership and could not finish it. Though I chose South Korea, all the regions were North Korean ones.
It is not the first time I found this kind of problem on ProZ.com. When I first registered on ProZ.com, I didn`t understand why my local time on ProZ.com account was GMT+8:30 instead of GMT +9. Later I found GMT+8:30 was North Korean Time and edited it right. Still, I see many fellow South Korean members with 30 minutes wrong time zone.
Next, I downloaded ProZ.com app and checked my profile. It said my nationality '북한(North Korea)' so I reported this bug and got it fixed.
This South/North Korea address issue is just getting annoying now.
Thanks for reporting, and my apologies for the inconvenience.
All issues indicated by you should be already fixed. I also see that your upgrade has been already made successfully.
Hope this helps.
