I’m a bit confused, why did you expect the balances on two different sites to match?
Every site should have its own set of transactions, and therefore user balances.
(I assume that you have connected both sites to the same wallet, something that I would advise against because it introduces a single point of failure for both sites in case of a hack. But in any case, just because the wallet balances match does not mean that the user balances should also match.)
Let me know. Thanks.
