This is peculiar: seemingly identical extrusions produce different results.
Whichever extrusion is executed first forms a closed rectangle
Whichever extrusion is executed second forms a U-shape (one side is not completed).
 
Web VPython 3.2
rect = shapes.rectangle(width=.1, height = .1)
path = paths.rectangle(width = 2)
extrusion (path=path, shape = rect, color=color.red, pos = vec(0,-1,0))
extrusion (path=path, shape = rect, color=color.red, pos = vec(0,1,0))

The order does not matter; whichever extrusion is first gives a closed shape.

Any thoughts?

The following works properly, so apparently the bug is that the extrusion machinery overwrites the path:

rect = shapes.rectangle(width=.1, height = .1)
path = paths.rectangle(width = 2)
extrusion (path=path, shape = rect, color=color.red, pos = vec(0,-1,0))
path = paths.rectangle(width = 2)
extrusion (path=path, shape = rect, color=color.green, pos = vec(0,1,0))

Thanks much for the report.

Now fixed. As usual, you might need to clear your browser cache in order to get the update.
