Battle arena Shop

Hi! I'm new at playing this and first of all I want to apologize in advance if there is another thread discussing this already. I did a little research but I didn't find anything to clear up my doubt.
My problem is I don't understand how does that "battle arena shop" works, the one where you can trade those silver bricks gained in the PVP battles. I want to buy fragments of a certain character but they don't show up, and when the shop automatically "refreshes" every 5 hours (or when I refresh it myself by using crystals) I still only see the fragments of the same characters available again.
Is it a bug? Do I have to unlock one of those characters to get the possibility to buy fragments of a different, random one? Or how does that shop work? Huge thanks in advance!
