Closed spline bug with LibreCAD

I created a simple closed spline in LibreCAD, exported to DXF.

It works fine if the spline is open, but if I use the 'Closed' option, the spline does not open properly in any other software I have tested except LibreCAD.

For me the issue is repeatable with any closed spline created in LibreCAD.



I am using Version 2.2.0.

Anyone have any idea what the problem is or how to fix?

This was just reported on GitHub issues (#1598), so there is no fix yet.

It is probably a misunderstanding or misinterpretation of the DXF reference and presumably located in libdxfrw, our DXF im-/export library.
