Automatic contour lines recognition from a DXF/DWG Land survey CAD file shows elevation values at "0"

I've generated my Contur Lines from a DXF/DWG Land Survey CAD file but it seems that the relating elevation values are "0" which is of course a different value to what is shown in the Label.

To be sure to acquire the Contour Line's elevation value, the recognition procedure, that reads data directly from the CAD file, needs to get the elevation data from the "Elevation" field. Such data isn't acquired from the Text Label next to the contour line.
