Extra outlines when exporting as DXF and SVG??

Why is this happening? I'm trying to import the DXF into CAD software and it's not working well because of these extra outlines. I see none of these lines within my drawing. I viewed the drawing in outline mode and nothing. I had drawn the image using the curvature tool with fill set to transparent and set the width to 0.96mm. I overlapped all of the strokes and when done I expanded all of them and then hit divide in pathfinders. I deleted the overlapped bits I didnt want and when done I hit trim and then merge in pathfinders. It looks fine, but when I export, as DXF or SVG, im getting all of these extra outlines that are super close to the the actual outline? I dont know what's going on. It's seems like it would be such as simple thing im trying to do.

I did a simple test with one stroke over the other, then expanded, divided, deleted a portion, then trimmed, and merged and it worked fine. I dont know why it's doing it with one but not the other. 

I attached 4 images: Two are of AI in outline mode and the other two are a close up of an SVG and a DXF.
