E.g. if I have a token with 6 decimals and a utxo with 100 tokens of that kind, account-utxos would print something like "amount":{"atoms":"100000000","decimal":"0.001"}. I.e. the amount of atoms would be correct, but the decimal amount would be calculated using the default number of decimals.
Same happens for standalone-multisig-utxos.
Rpc calls, like get_multisig_utxos, also have this issue.
