Bound fantasy hockey collectibles

Hey! ive been trying to use fantasy hockey collectibles, but they wont fill into the set. I have three collectibles, two from trading in 2 92 players and one from a challenge. All three are marked as bound when i find them in my collection. Oddly, they don’t appear as bound if i look them up in posting an auction. Obviously bound collectibles makes no sense. What should I do?

thanks!
