Using ArcMap 10, I have set ArcMap 's Data Frame Property  to have a UTM coordinate (NAD 27) but when I review the property value it seems to have using both Projected and UTM coordinate system! Please take a look at following image, As you can see the selected coordinate system is
NAD_1927_UTM_Zone_14N but in current coordinate system after the UTM one the GCS_North_America_1927 ... also is listed? Can you please let me know if this is normal or not? and why? please?
