I was having an issue where my cut line was cutting and turning around and cutting back over itself. The post below said to look for double lines, which I didn’t have in my Illustrator file. When I went back in and looked again, my stroke was set to be on the inside of the shape rather than the center, so the GF was going back and adding 1/2 a stroke width of cut .
Thought I would add this just in case anyone else runs into this too.
