Glitch or.....

So with the new gift update I have been getting a lot of diamonds! Thats the good thing. The glitch thing is that in the sticker collection, they used to be a thing that you can get a non-duplicate, rare or wardrobe item for ten to twenty diamonds! Then it suddenly disappeared for me.? Please solve this for me.
