I have send out a discussion regarding this issue. When you just use the country field - look what happens.
1. For the last few days when you just type in the 1 field Drakenstein - you get that Limpopo, in Limpopo, instead of Drakenstein, Cape.
I have this ugly "gewoonte" to always open all the fields and then check. SO yes, I have already changed a lot of them but am sure there are still thousands.
Maybe they - who did this activity - saw way ahead in the future. A thousand of these profiles dates back to 1700-1800.
The auto fill for places is seldom right for South African addresses - for this reason I never auto fill - I always manually complete all the place fields. I have found that the fields are not correctly in using the auto generated tab.
