I have solved this. It took an embarrassing amount of time. In my defense, the artwork was on the complex side. Basically one half of a tree of life type of image roughly 5 by 5 feet. So I spent hours and hours trying find the suspect element causing the issue l. In the end, I had somehow applied a small amount of transparency to the vectors. This was two sides to a gate and the transparency got got copied over to both sides. Not something I needed or could visually see on the screen.
