Hi,
Are you taking into account the north rotation?
The below may help, coords can be tricky:
Getting Coordinates from Survey Point - Revit - Dynamo
Solved: Revit Dynamo - Creating automated pile coords - Autodesk Community
Also btw to avoid confusion I would swap the eastings and northings in the label, eastings should be given first. And preferably change units to metres with 3 decimal places.
