For some reason whenever I export a feature class to a shapefile I have been getting duplicate fields appearing at the end of the attribute table of the exported shapefile. The fields that are duplicating themselves are the fields that have subtypes. This is occurring for all feature classes that I export that have subtypes. It does not occur to feature classes without subtypes. Whenever a field is duplicated it is headed with 'd_(field name)'.
For example: I export a feature with the following fields that each have subtypes:
DATA_SRCE
ENV_VALUES
CAP_METH
In the exported shapefile they appear as duplicates at the end of the attribute table as this:
d_DATA_SRC
d_ENV_VALU
d_CAP_METH
Has anyone had a similar problem? Or might know why this is happening?
