[Developers] South Carolina weirdness

[Will Moffat]

Hello,

The trivial query below fails because South Carolina has two values  
for "capital" even though the schema says the property must be unique.  
This will break applications written against the schema. Are there  
tools that warn about this problem? Should they be exposed in the  
Freebase UI?

I cannot delete the extra value 'Charleston' using the Freebase.com UI

Weird thing no. 3 is that I cannot see any record of "capital" ever  
being changed in the history view.

location/us_state"}]
