I have noticed some boxes of 197 on auction sites with a "LF primer" label on the box. Anyone know details if the 197 is now lead free too?

Hi, I just purchased 40 boxes of "new" 197 Official FN 5.8 X 28 Ammo from Gun Broker.com. All of the boxes that I received didn't contain a clear sticker which seal the box. Is that weird ? Input appreciated.
