CivilConnection2021 5.0.1 - test fails (from C3D to Revit)

I did a test with “D4R_CivilConnection_TINSurfaceToTopography_LandXMLTriangle” in Revit version 2021.1 and have an error (see fig. 1).

Could this be due to CivilConnection2021 version 5.0.1? Because in the past I did’t have problems in Revit 2020.2 .

Fig. 4 = should I do something with “CivilPython” ?

Thanks in advance!
