I use PowerPoint's drawing objects to create art sometimes. If you make the stars' points skinny, the outline goofs up like that. Wouldn't surprise me if that's what's going on with their program.
As for packages having it, they probably made a couple batches like that then took the stars off. I'd leave it MIB for the moment in case that's what's happening; if there's an uncommon packaging difference, I can see it being worth more.
