cut line printed

Stickers are awesome... I just don't understand why the cut line (that was on a separate layer) got printed. I validated it because I thought it was normal to see it, as I validated the sticker sheets two months ago. It printed the octobear as a sample so no big deal. I still like what you do and will be more careful on my side with my files :) Question: Was I not supposed to put the cut line? (so I know for next time!) Thank you, Flavie
