In the India Theme, you can assign a state to more than 1 region...
So you can assign same region name to 2 or more regions on the Map.. (This is a BUG)
There can be 2 Delhis or 2 Karnatakas or Keralas...
This should be rectified.
This can be prevented by removing the name which is already assigned to a different region from the list which appears while assigning a region..
OR
Giving an alert mentioning that this name is already assigned to another region...
