Omission in interpolation calculation Z_GROUND in PROFILE table

Omission in interpolation calculation Z_GROUND in PROFILE table
Affected PLE version: 4.2.3

Hello, there is a omission in the calculated values of Z_GROUND in the PROFILE output table. An example is given below:

   

The educational PLE project file (zipped) has also been attached for the analysis.

At the 'start' (node 6) and 'end' (node 22) of the bend I get a Z_GROUND of 1707.1 mm in AutoCAD. PLE gives in the PROFILE output table a Z_GROUND of 1655 mm at the bend ends, see picture below:

   

This calculation error is always reproducible when bends are used in the POLYDIF.
Column W_LEVEL in the PROFILE table is also affected with the same error.

I have also tried different configurations in AutoCAD to verify the Z_GROUND. The error of the Z_GROUND at bend nodes are structural in PLE.
It is important that the Z_GROUND is correct, because PLE uses the PROFILE output table in the Soil Model Wizard to calculate the soilparameters.
