ORD Connect Edition LandXML import/export error and problems to/from InRoads SS2

I am trying to work with ORD CE (OpenRoads Designer v10.8.0.41) and InRoads SS2. Mainly to design and share alignments. I have no problems importing alg files from SS2 to ORD CE via import utility.

There is however peculiar error with LandXML import to IR SS2 from the ORD CE. The profile in the  is "wrong". The levels of the elements have different values, grades are different than the same points/elements in the ORD CE. 

Three first elements of the same profile in ORD CE

Linear POB -600.000 200.514 0.020 PVC -333.050 205.853 0.020 266.950 0.000 0.000 0.000
Parabola PVC -333.050 205.853 0.020 PVT 480.950 207.074 -0.017 814.000 0.000 0.000 0.000

the same elements after import to IR SS2 from LandXML

Almost all parameters are different. Can anyone explain this?

Secondly the ORD CE crashes constantly on import from LandXML.
