blocked jewels ???

hello, I’ve been playing this game for a while and I really like it. but this week I realized that the jewelry I had in the bank was ‘invalidated’. I also saw the name ‘legacy upgrade jewel …’. i would like to know why this happened to me? I spent hours playing to get them I think this is unfair and discouraged to play, I can’t use it, I can’t sell it and it just doesn’t fit anymore? help me get them back

you can stash them and use it as fragments to craft jewels.
