Remedy suggestion

When trying with location features, I discovered that some locations were duplicated. After further checking, I find that it is due to the state/region name that one of them with leading space, making GD thought that it is a different State.

Is there a quick way to fix this error?

May I also suggest to built in a trim leading and ending space for string data, this helps standardize data and minimize unintentional space left like this. We always do this process for string input fields back in the old days. just a friendly suggestion to make GD more robust and error tolerant
