Getting Elevations from Surface for Cogo Points

Hello there!

I was trying to Get some Elevations from a Surface for some Cogo Points by creating a clearance report from the specified Surface, The issue is that when i checked the Northing & Easting of the Cogo Points, they were different than the specified ones, which means the elevations are not obtained rightly, so is there any way to get this thing right.

Thanks & Regards,
