Northing Easting Point Schedule

I am having some trouble with a Northing Easting Point Schedule that I am generating for a small project. Because the project is very small and the insertion point of the base file is quite a distance away, I have decided to insert the northing easting points relative to a custom UCS. I have followed the instructions in your documentation and all appears successful when I insert points and/or northing/easting callouts (meaning that clicking on a point and looking in the properties palette indicates that my point is located in relation to the 0,0 of the custom UCS and the callouts indicate the correct coordinates also in relation to the custom UCS). However, when I run a northing easting schedule from the grading manager, the point schedule lists coordinates that are relative to the WCS. I have tried generating this with various ucs settings, exporting to spreadsheet, etc, all to no avail. Is there something critical that I am missing? Any help would be greatly appreciated.

Thanks!
