I suggest you to check extrusion direction property too. I had similar question when extrusion direction (Z axis) was non-standard

Also, if possible - attach dxf file

i think the problem is that if the bulge works like this:
bulge > 0 or bulge < -1 counter clockwise
bulge < 0 or bulge > 1 clockwise
but in the converter is only look for 0 >< but after 1 or -1 is change the direction.
