found a strange behaviour comparing some stats for several collections for example azuki colleciton has 10000 items, but the api returns when you count 10001 for Genuine Undead its even more weird they have exactly 10000 nfts but api returns 10018 and much more unique holders than there should be. im sure that everything on my side is correct, tested and checked several times. Simply just add together all array lengths
