Problem with polyline shape file

[ekleiman22]

Sample Shape.txt

Hello,
I use your code to convert shape files to json and to show on the map. In most cases it works wonderful, thank you very much. But I have some shapefile that is shown wrong. I attach sample images:
sample1.jpg shows how this file is shown in http://www.mapshaper.org/ and it is what I expect.
sample1_wrong.jpg shows what I get using your code. Also I wanted to attach sample.shp,
but this site does not allow me to do that. I can send it to you if you'll explain me how to do that.
Updated: I added Sample.shp as SampleShape.txt.
Any help will be appreciated
