I'm trying to use the ArcMap Standardize Address tool (http://desktop.arcgis.com/en/arcmap/latest/tools/geocoding-toolbox/standardize-addresses.htm). I'd like it to change "West" to "W" in the PreDir field as it shows in the example, but my results are actually the opposite. Addresses with either "West" or "W" both get "West" in the PreDir field.
Why is this happening and how can I get it to function as the tool describes?
