Hey Jackie! Kristina here.
I, too, have noticed those pesky indentations. However, I think the way you feed it into your die cutting machine will help. I've noticed that when I feed it into the machine with the short end first (the most stars or the least stars), the indentations appear. But when I turn the die 90 degree so that the long edge goes in first, I get no indentations.
Have you tried turning the die around to see if you get a different result? Hope our dies aren't defective. I've heard from multiple people that they don't have this issue at all.
