Random behavior of PolyCurve.Offset - Changing Sides

Im trying to make an Offset of this Polycurve made from an imported Polyline . When making a small change on the original polyline in Autocad, the side of the offset change from the left to the right side randomly. Can anyone tell me what Im missing? Or is it a bug?
Also, the offset should be a Polycurve instead of an exploded curve.

It is a bug:

It might have been fixed in the latest release, but I have not tested it.

Thank you very much, Anton.
I am currently using Dynamo 2.12.
I am checking here if we already can update it.
