Wrong curve direction when import dxf

Hi, recently when I tried to import dxf file, the curve direction when dxf is imported is in opposite direction (some of the curves are in right direction though), I tried to convert all line to polyline, explode them all, but no luck. Is there anyway to fix this? Here I attach the .blend file and .dxf file I’m trying to import (inside the zip).
