REVIT Topography height of 0.0 is at Level -0.30m

Dear All, 

I have been breaking my head for hours, but I can't resolve this.

My topography when inserted at 0.0, should be at level 0, but for some unknown reason its at Level -0.30m

Can someone advise how to fix this?

See attached REVIT file.

Is it a link?  Just select the topo in an elevation view and move it up 30 cm.

Toposurface Internal Points (the ones in Sketch Mode) are ALWAYS relative to the Internal Origin of the Project.  They have no bearing to Project Base Base or Survey Point on which your Levels Elevations are based.  

...Spot Elevations that you place on the Toposurface are also relative to the Survey Point or Project Base Point like Levels.
